General :: Boot Label Changes Using Kick Start
Jan 30, 2011
I am customizing CentOS and doing the entire procedure through ks.cfg file. Everything is been configured properly except the boot label. I would want Boot label to be customized rather than the default one. Is it possible to achieve this using kickstart?

I have ks.cfg and file.iso burned to a DVD. Both files are at the root of the DVD. Besides that, I also created a folder and keep some drivers in the folder.
I inserted the CD and reboot the server ( which already has a red hat 5.3 that I installed before, I want to erase it using kick start ).
Howver, I just can't get into the much said "boot prompt".
Do we need to press certain hot key during certain stage of reboot?

I have problem while configuring kickstart installation in rhel 5.2 .
I have followed bellow listed steps.
i, Copied iso.img into my server
ii, # mount �o loop iso.img /tmp/iso # cp -a /tmp/iso/* /tmp/iso_new/ # system-config-kickstart - - generate ks.cfg ( creating kickstart configuration file) # cp /root/ks.cf /tmp/iso_new/isolinux/ ( As suggested by red hat I have copied ks.cgf file into /isolinux/ folder.
iii) mkisofs -R -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o /tmp/new_1.iso /tmp/ iso_new # to create bootable disk
iv) Then started the system using this newly created iso image through HP ILO console and the system got booted successfully with boot prompt.
v) After executing the linux ks=cdrom:/ks.cfg from the boot prompt, we got a error by saying there is no CDROM deducted in your Machine and the installation got terminated .
vi) As per my understanding the ISO image is mounted as Virtual CD-ROM (/dev/scd0) in HP ILO.
Why the we are getting CD-ROM related Error ? How we can avoid this error? Is there any other set of configuration to achieve this ?

I have a USB thumb drive that I just partitioned using the 'fdisk' utility in Linux. Now I am trying to learn the command that will allow me to format the drive as 'fat32' while also setting the disk label on the device as "ocz_usb" when the drive gets mounted. Does anyone know the command I would use that will format the USB drive and properly set the disk label at the same time?

I am a newbie to Linux and I am using CentOs. I am trying to create a new partion on my CentOs VM. I create a new primary partition using fdisk (I use the command fdisk /dev/hda). After I create the partition and use partprobe to write the partition to disk, I try to give the new partition a label. So, I use the command e2label /dev/hda LABEL=test
However, when I enter the command e2label /dev/hda3 , it doesn't display the label for the newly created partition. Am I doing something wrong here? Is the syntax of the e2label command wrong when creating the label for the new partition? Did I miss a step after writing the new partition to disk.

i was trying to re-label my flash drive and i manged to with the help of this command
mlabel -i /dev/sdc1 -s ::test
what does the -i option means cause after i read the manual pages i couldn't find it there. mlabel only takes the "v" "s" "c" switches and no "i" and when I remove the -i option from the whole command don;t work and i can't re-label. its just driving me crazy that every one is using it and no tells what does it do.

I use to know this command but lost it and did not note the entire command on my Linux cheat sheet. Someone once showed me a simple very easy command I could use to simple format a USB flash drive as FAT32 and in the same command also name the label of the drive.I have the device /dev/sdc1 and I am formatting this as FAT32 so it's compatible across multiple systems but also want the drive to have the name 'my_usb'.

I realized that my understanding of UUIDs in Linux to specifying hard disk partitions may be erroneous.
The proverbial wisdom is that one should not use hard-coded device specifications in fstab and in the boot menu.lst, such as /dev/sda1 etc. The reason normally given is that if hard disk order changes or the order of partitions change, then the entries will be incorrect since they are hardcoded to partitions following a specific order.
So my understanding was that using hard disk labels, in the form of LABEL=xxxx, or UUIDs in the form of UUID=some-uuid, would prevent these problems when disk order or partition order changed.
I decided to avoid the use of LABEL in case I wanted to change the LABEL on a partition to make the names of partitions more easily identifiable. I then thought that UUID was ideal since it never changed for a partition no matter even if I moved that partition to another drive or added another hard drive and thus changes the order of hard drives on my computer. I essentially thought that once UUID was determined for a partition, it never changed but was somehow part of the partition in the hardware of my computer.
Then I became curious of how a UUID was determined. I did this because I often make backups of partitions on external SATA drives and wanted to make sure that somehow the backup would not duplicate whatever Linux considers the UUID of a partition and present a Linux distribution with two UUIDS which are somehow the same and therefore confuse the Linux distribution to the point that I could not use it. I am aware that UUID means a unique id, but I wanted to make sure I understand how that unique id is determined in Linux. This is especially true since the tool I use to make backups of an entire partition is a Windows application, and not a Linux application, and I wanted to make sure that the backup partition UUID would not duplicate that of an existing partition.
In my very brief research in how a UUID is generated under Linux it appears that it is not something that is part of the hardware of the partition itself but rather a number generated by some parameters of the partition, one of which is the partition order.
If it is, it means to me that if I move a partition from one place to another, even on the same hard drive, or to another hard drive, a Linux distribution will no longer find the partition based on the UUID. In that case it seems as if the UUID is subject to the same weakness as the device specification in fstab and menu.lst in that the order of a partition or the placement of a partition on a particular hard drive will cause the designation to no longer refer to the same partition. In which case it appears to me that only the LABEL parameter is not subject to this weakness and as long as I keep distinct labels for all partitions on my hard drive I could theoretically move them around at will and a Linux distribution will find them correctly. I am aware of course that my computer must always find the boot partition to be able to boot a Linux distribution, so moving Linux parttions where I want them is subject to the ability of my computer to find them from the MBR of my hard drives. But in the main it now appears to me that the best way to insure that moving partitions does not keep a Linux distribution from botting correctly is to use LABEL, and not UUID, in fstab and menu.lst, and of course to make sure that if I decide to change the LABEL of a partition that I must change its entry in fstab and possibly menu.lst before rebooting that distribution.
If I have been wrong in my latest surmises I would appreciate being corrected, as the information I found on UUIDs and how they are generated may not be correct. Also if there is more exact information on exactly how partition UUIDs are generated in Linux I would appreciating anyone pointing it out to me.

When I installed Ubuntu on my system (a year or so ago) I forgot to add a BIOS Boot Partition. This is something of a problem considering that the partition type for my 2TB drive is GPT. Hence, whenever grub is updated I get a warning:
Code:
/usr/sbin/grub-setup: warn: This GPT partition label has no BIOS Boot Partition; embedding won't be possible!.
/usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and its use is discouraged..
Installation finished. No error reported.
[Code]....
If so, what is the rough sequence of commands to create the partition (without disturbing what is already there) and then setting it as a BIOS boot partition.

I have used fdisk to create two new partition.
Before this partition, I had 6 partition of which /dev/sda6 was the boot partition. I deleted /dev/sda5 partition and hence the earleir /dev/sda6 became /dev/sda5. Now I created two new partitions /dev/sda6 and /dev/sda7.
Due to this change in device label of /dev/sda6 I am not able to boot my computer.
Is there any method to change the disk label of /dev/sda5 to /dev/sda6 ?????

I have a client that needs 5 machines updated. They are all running Ubuntu 9.04. Long story short, I can only log in over VPN for the time being (as they're in another city).
That said, is there any good way to remotely update the systems without the need to remain logged in (e.g.via SSH)? I'd like to simply kick off the updates and check back in at a later time.

I am running Kubuntu 11.04 and I use the standard "Blank Screen" screensaver. I want to start a command every time the screensaver starts and to stop it when the screensaver stops.
My idea is to copy the "Blank Screen" screensaver and add a couple of my own lines in the source code ...
but I have some trouble finding the correct files.

I've configured ssh on opensuse a few times without issue, and to get it to run at boot I've used 'chkconfig ssh on' and it's done, sshd starts at boot.
I've recently started to use Debian 9.04, and for the life of me I cannot get ssh to start at boot, or to be more exact, if I try and connect via ssh I get 'Network connection refused' and 'ps -ef|grep ssh' shows that it is not running.
1) If I start it via '/etc/init.d/ssh start' it runs fine until the server is rebooted
2) I've done 'update-rc.d -f ssh defaults 20' it returns that the links are already in place
3) During the boot up process I can see 'Starting openBSD Secure Shell' (it was also at this point I discovered that BOOTLOGD is not enabled by default)
Another strange thing, when I edit /etc/motd it is not retained after a reboot.

I have a service/daemon that won't start from boot. I have used the chkconfig --add <script name> command that went ok I also used the chkconfig <script name> on and that seems to be fine and I have made the script executable Chmod 777 <filename>. By all account it looks like the script is running at boot the the services has not started. When I do a ps -ef | grep ndb_mgmd this process is no there. the script can be run from the console and sems to run fine!
