Debian Installation :: Separate Functional Partition / User's Account?
Nov 16, 2010
How can I implement this: I encrypt a partition using LUKS, and store personal data on this partition. Then create a user account that solely deals with this partition and insulated from the Internet. Normally for each boot I do not even need to mount the LUKS encrypted partition, and when I mount that partition under that special user account, I can make sure that the Internet is cut off.
I'm going to do the installation these days, could you provide a brief sketch regarding what steps I should go through to implement the above result?

I want to jail Skype into its own process and not the one I login with. That way, if a hacker breaks in, it's limited to this process and only the limited functionality that that user account has. The thing is this -- thousands of Linux guys run Skype, but Skype is hardly ever updated or have security patches, and we run it all the time. It seems like an easy avenue for an exploit. As well, my iptables firew all blocks input connections that I have not established, but Skype is an established connection. How do I create a Bash script that launches Skype under a separate user account?

So I need to become the root user in order to edit a grub file in a seperate partition, so I can get back into this partition. How can I become and stay as root user in the desktop environment? (I know you shouldn't do this, but I need it.)

I just did a clean install to wheezy on my desktop (figured it was safe enough) and I found out my preferred keyboard, the Logitech 'Wave' K350, does not work on the wheezy installer. I tested to see if the mouse would work (M510) and it didn't work either. It works (or at least it did a few months ago) fine on the Squeeze installer. why my K350 didn't work on the install. It's just your typical wireless keyboard & mouse combo.The K350 works fine after the install.

My Debian System GUI (Gnome desktop) is not functional (which means I can't take snapshots of the codes, use openofice, edit photos, watch movies and am using a different computer) after I installed updates when I was notified about updates by the "system notifier icon".
The "hal" package is broken, and the GDM informs, after unsuccessfully trying to boot the GUI thrice, that kbd, nvidia and x11

I was surprised not to find an existing thread on this anywhere, as I would expect this to be a common problem: I have the following partitions on my eee PC 100HE:
10GB Windows XP
5GB Linux Mint 8
5GB Ubuntu 9.10 NBR (awesome distro by the way!)
130GB Home partition shared by Linux Mint and Ubuntu NBR
2GB Swap partition shared by Linux Mint and Ubuntu NBR
I installed Ubuntu NBR after Mint. Immediately after install, the panel layout, menus and colour scheme were slightly messed up - presumeably because they had been "adopted" from the Mint settings in the home folder. I corrected them easily, but now I have the same problem in Mint. Is there any way I can get both distros to use the same /home folder, but different settings (i.e. the /home/username/. folders)? Can I get these settings folders put on a different partition for example?
And is this problem due only to the fact that these are 2 Ubuntu-based distros? Or will I have the same problem if/when I replace Mint with another distro, such as Fedora or Moblin?

I run several OSes (all Linux) on my computer. I set a separate partition for each one. I want to run Fedora 13 LXDE mainly for a game or two that are in the Fedora repos but not in any others, so I will not need a lot of space. But I want to make sure there is enough room for the OS.
I want to be able to play CloneKeen, so I will need enough space for that. I may find some other games, as well, so I will need some extra space. I have my other two OSes on six GB apiece, and Peppermint actaully uses barely half of that. Will 6GB be enough for a basic Fedora install with a few games installed? I will not really use Fedora for anything else, probably.

I made the mistake of using the command 'adduser' on an already existing user. I was incrementing a name and mis-typed. Now the account refuses to recognize the users password. The user can get in.
I tried resetting the password as administrator (passwd 'user'), but when the user tries, the new password isn't recognized.
I tried expiring the account password (passwd -e user). The user gets prompted for a new password, but the new password still doesn't get recognized.

Is there a way to setup a separate /home partition during a new installation of Ubuntu? If so, how. I've found guides about how to do it after installation, but it seems there ought to be a way to do it that way from the very beginning.

Trying to dual-boot OpenSolaris and FC10 is difficult because Solaris grub doesn't know about ext3 and Fedora grub doesn't know about ZFS. I was able to rescue my FC10 installation by creating a new FAT16 partition and restoring /boot to it from a dump, and then doing a grub setup to it. A complication is that anaconda doesn't seem to be able to find /dev/md0 (both the Solaris and FC10 installs use mirrored disks).
This process moved the FC10 ext3 partition from /dev/sda3 to /dev/sda4, but the other half of the mirror is still /dev/sdb3.
When I boot FC10 I get a "can't load image" error from grub, but it still loads FC10 successfully. It makes no difference if menu.1st/grub.conf has "root (hd0,1)" (the FAT16 partition) or "root (hd0,3)" (the FC10 ext3 partition).
If a future yum update were to try to install a new kernel, my FAT16 partition would not be updated. It seems to me both these problems might be solved if I could move /boot from /dev/md0 to /dev/sda2 (/dev/sda2 is the FAT16 partition).
Rather than go through yet another install, would the following work?
from FC10, move /boot to (say) /boot.0
mkdir /boot
edit fstab to include "mount /dev/sda2 /boot"
If I try this and it doesn't work, I can't see any way to undo it since anaconda doesn't seem to be able to mount /dev/md0. If a grub guru sees this, perhaps they could suggest a better alternative, or if not, whether this will work or not.
Additionally, although there are two alternatives in menu.1st/grub.conf, grub doesn't display a menu - it goes directly to boot. Any idea why? I suppose this might be a Solaris stage1 grub problem...
Since FAT16 doesn't support links, it isn't possible to link grub.conf to menu.1st. Are they both required?

I am triple booting
Windows xp
UBUNTU 10.04
Fedora 13
Everything works fine, the setup went very well. But I got to thinking (A dangerous thing for me). In Ubuntu I am using separate partitions for / (root) and /home. I was wondering, during install of Fedora, could I use the separate partition I am using now for both root and /home for just / (root) and use the Ubuntu /home partition for Fedora (set the mount point for /home to the same partition as I did for Ubuntu and not format the drive)? This would allow me to seamlessly use the /home partition and not require duplication of files. I can mount the Ubuntu /home dir while in Fedora.I can share the /home partition with two different installs of Ubuntu (been there).

I want to move my home directory to a separate partition so I can install the new versions of Ubuntu without losing my data. And while I'm at it, what other important directories should I move to separate partitions? And how do I do it? I'm guessing that the /boot directory should also be moved to its own partition too, yes? Because it has the GRUB in it, and if I removed Ubuntu to make way for a newer version of Ubuntu, I'll just get an error because the computer can't find the GRUB that doesn't exist anymore, right? And also, if I move those important yet-to-be-listed directories to their own separate partitions, how large should those partitions be?
I don't want to miss out on the upcoming Lucid Lynx (If it will work in the first place, of course ) By the way, I have an Ubuntu-Windows XP dual-boot system. I'll attach a screenshot of my partition table from GPartEd. You can see that I have about 300 GB. The largest partition is Ubuntu.

Many Ubuntu users seem have their /home folder on a separate partition (better security?). I have a OK dual-boot installation (Win7+Ubuntu 10.04) - should I try to move my /home folder ? If so, how ?I DO NOT want to get into any troubles with my existing setup !I have free (unallocated) disk space both outside and inside the extended partition which is used for Ubuntu (90 GB, Ubuntu is 60 GB ext4 + 7 GB swap).

While installing with a separate /boot partition I cannot get two distinct copies of ubu installed on one machine and be able to choose between them. Each is installed on a different hard drive. x64 versions. I've had this issue both ways:
Stepsinstall mythbuntu
install ubuntu
Result
Two entries in grub. Both cause ubuntu to boot
Stepsinstall ubuntu
install mythbuntu
Result
Two entries in grub. Both cause mythbuntu to boot Grub 2 is so unfriendly for fixing these things. I don't know where to make changes. Ok, Grub 2 is very powerful, maybe it's the lagging documentation, or lack of tutorials that is the problem. But I don't know how to fix this. Do I start over without the /boot partition? Do I bail on ubu?

I recently put ubuntu on my laptop in hope that most of my games would run through wine, some did and some didn't.
Anyway, long story short, I have ubuntu on my laptop and I want to re install windows onto a separate partition, keeping my ubuntu instillation in tact and set as my deafault OS.
I'm very new to ubuntu and the only guides i've seen are fairly complex. I was just wondering if anyone could point me in the right direction? p.s. Is there maybe a way to create an image of my current ubuntu nstillation/settings/apps etc. just in case I do something wrong and lose everything?

I haven't been using Ubuntu for a couple of years. Yesterday I decided to fire up my ubuntu box and upgraded from 8.04 to 10.10.
The upgrade went fine, but when I boot it tells me that the /home dir cant be mounted. It allows me to Wait, Skip, or Manually mount it. If I skip I can log in and mount the partition that contains my /home folder so I know that nothing is corrupt. I'm sure my fstab just got overwritten during the upgrade, but, since its been so long, I don't recall how to (correctly) fix it back.
Cliffs:
--Upgraded from 8.04 to 10.10
--/home dir is on a separate partition & is not mounting properly
--How do I set it up so that my /home dir mounts on boot?
I'd just try messing around with fstab myself, but I really don't want to lose any data.

Compiz settings, my entire GUI would freeze up after the startup splash. It did the little ubuntu jingle and so on but wouldn't actually load up the desktop. I would've booted into recovery mode and deleted the settings that were messing it all up for me, but pressing ESC during grub did nothing! So as a last effort I reinstalled Ubuntu (Karmic) from the live CD on the first partition only, but I don't know how to make the second partition (with my old /home directory) the normal /home directory. The instructions linked above seem to require having done the whole process of moving the partition (so as to create "old" and "new" dirs, etc.).
So there are really two problems here: 1) How does one restore things to normal when a few too many cheeky moves with the desktop effects turns everything to pot? And 2) How does one reinstall Ubuntu with a separate /home partitions

I will be helping a friend upgrade from 9.04 through to 10.04 LTS, and I am aware that the machine was installed with a separate home partition. I know a clean install is an option however I am tempted by online version upgrades with the thought that any apps they are using will be carried over. Is this a realistic hope? I know that medibuntu for example does not survive a version upgrade.

I've read several accounts of users who upgraded Ubuntu versions and ran into problems. I read that putting /home on a separate partition can make it easier to do upgrades. But it seems to me application versions and even the default applications themselves change so much between Ubuntu releases that I question whether it's a good idea to have all the "OLD" config files and settings that get stored in /home sitting around when running a new Ubuntu release.Does anyone think it's a better idea to just put the whole Ubuntu install (i.e., / and /home) on the same partition? And then when upgrading, backup, and then just fresh install everything (to get the cleanest possible installation)?

Noobish question on multibooting multiple Linux distros. I have four of the current major Linux distributions. Each has been installed and run individually (no other Linux distribution installed) in a dual-boot configuration with Windoze. No problem.
What I want to do is install all four Linux distributions and multiboot them. Reading the internet it would seem this is a simple task with GRUB. The short version being - install a Linux distro with a separate /boot partition for GRUB and use GRUB to boot the other Linux distros from the GRUB boot menu.
So I installed one of the Linux distros with a separate partition for /boot. The distro installer installed GRUB in /boot and correctly setup a dual-boot configuration with Windoze. GRUB was installed to the MBR. Next I installed a second Linux distro in its own root partition and told the distros installer NOT to install GRUB to the MBR, but rather, to the boot sector of the root partion of the second Linux distro. Installation was uneventful (and I could access the second Linux partition from the first installed Linux distro, things looked ok). Then I added to following to the installed (MBR - /boot) GRUB's menu.lst:
Code: title lixux distro 2
root (hd0,7)
chainloader +1 After which I rebooted the system and the new entry for the second Linux distro now appears in the GRUB boot menu. I selected the second Linux distro from the boot menu and got the following GRUB error: Error 5 : Partition table invalid or corrupt
[Code]....

When i installed the new version of debian on my laptop to try it out, i noticed that i can't sudo as my main account is not in the sudoers list and i cannot put me in because i'm not sudo.

I have to enter as a root account but don't know how, plus i forgot my root password.
note. i dualboot with ubuntu 10.04 and grub is managed by it.

Looks like I missed defining a /home dir during installation. It's been a while I have a spare partition now that I'd really love to use. Can you specify this still, or is it only allowed during an install?
