General :: How To Write To A Rc.sysinit On A Tempfs
Feb 25, 2011
my rc.sysinit script has:
if [ "$FACTORY_RESET" = "1" ]; then
echo 'Reseting to factory config'
mount -o sync,remount,rw /boot
[ -r /boot/default.cf.2 ] && mv /boot/default.cf.2 /boot/default.cf.3
[ -r /boot/default.cf.1 ] && mv /boot/default.cf.1 /boot/default.cf.2
[ -r /boot/default.cf.0 ] && mv /boot/default.cf.0 /boot/default.cf.1
[ -r /boot/default.cf ] && mv /boot/default.cf /boot/default.cf.0
mount -o sync,remount,ro /boot fi
And I need to change last one to rw or comment it out until I write some other part of the installation, otherwise the whole system is ro and I can't alter or install anything. I guess that when my system boots put everything into rw, create the system and then move everythiong into ro, so I am locked out. If I remove the SD card and put into another system, how can I access the script and change it?

While playing with my Linux box, I edited rc.sysinit in /etc/rc.d/ folder. But now when I boot into run level 3 or 5, I get complain that system cannot run /etc/rc.d/rc.sysinit. I boot into run level 1, and checked its permissions, which is rw-r--r-- . It should be rwxr-xr-x. I tried to use chmod to change its permissions, but it responded that "Read Only file system" Now how can I change its persmissions when in run level 1. In run level 3 and 5, machine does not boot. My box has Fedora Core 2 with kernel 2.6.20.

I recently installed Cent-Os on a server and changed the default partitioning to have 2 partitions - 1 main area for everything and a swap partition of 8Gb After installation I cant see the swap as a separate partition although there is a 16GB tempfs mounted as /dev/shm Is this right ?
fdisk -l shows :-
Device Boot Start End Blocks Id System
/dev/cciss/c0d0p1 * 1 13 104391 83 Linux
/dev/cciss/c0d0p2 14 17844 143227507+ 8e Linux LVM
(first partition being non-lvm boot)

I have a minimal installation of Ubuntu, with lxde-core and some other apps I really use. Sometimes when I start the system, it hangs and nothing else happens. I hit Esc and then I see:Code:init: Failed to spawn rc-sysinit main porcess: Unable to open console: Input/Output error.I get stuck there, and the only thing I can do is to hold the power button, shutdown, boot again, and pray it will boot fine. Sometimes it does, sometimes it doesn't.

I am using kernel 2.6.32.21, and my hard disk is West digital WD10EARS-00Y, 1TB. This disk is just for data, I made 2 partitions on it, each has half. And I have another small disk for system. I am using ext3.
this is my fdisk /dev/sdc
Device Boot Start End Blocks Id System
/dev/sdc1 1 60800 488375968 83 Linux
/dev/sdc2 60801 121601 488384032+ 83 Linux
[Code]....
I ran some dd to test the write throughput on /dev/sdc2. If I run it in /data2, I got around 70MB/s. If I create some directory, say /data2/dir/, and run dd again, I might get 60MB/s. Sometimes I still get 70MB/s, sometimes I get 60MB/s, differs for directories.
I wonder if this is because the allocation policy of file system, ext3, or this is from my hard drive?

I have XP on the boot HD, Ubuntu 8.04 on the other HD, and grub on the MBR of the Windows side. Then the Windows HD went bad and I need to get grub onto the other side so I can change the boot sequence to what was the second HD (the Linux one) and abandon the Windows side. Booting from a live CD is no problem, but I can't figure how to install grub onto the Linux side, which has been partitioned. I know where menu.lst is, and have backups of it as well.
Is this something that needs supergrub, or can a simple write to the proper place be done in a terminal window?
If switching the boot sequence is not enough (don't see why it shouldn't be) then I can also switch the jumper configurations on the two hard disks. But I don't think that should be necessary.

I have an old Mac OS (Tiger) and the new OS are not backwards compatible with computers as old as mine. In the reading I've found they explain how to partition the hard drive, but this is not what I want. I only want to have the Linux OS.

On my laptop for testing, I simply chown each subdir of /var/www to my myuser:www-data. But, now that I am setting up a public facing server, I'm wondering if this is the proper way to do so? If not, what is the best way to allow a non-root account to write to /var/www.

I just did a fresh install of Fedora 11 and added Raid 1 following this tutorial: [URL]
Now I see the filesystem when I open 'Computer' in the GUI, and I open it and see 'lost+found', but i can't write to the drive. The option is simply greyed out. And when I view Properties on the drive and go to Permissions, it says 'The permissions of {driveid} could not be determined.'

I want to keep a trace of the URL I visit, so I use a command line like this:
tcpdump -ien1 -v -X 'tcp port 80' | sed -nl
's/^.0x[0-9a-f]{4}:.{43}(.)$/1/p' |perl break.pl |perl -pe
's/(GET|POST).(.*?).HTTP/1....Host:.([a-zA-Z._0-9-]*)../"
BEGURL
[Code]....
I also tried redirecting stdout and stderr to /tmp/out, it's still empty. The file has write access. I have no idea what it can be. Is there anything else than stdout and stderr?

I am using OpenSuSE 11.0
KDE 3.5.9
Konqueror
I was able to copy 227 images to a brand new 2GB memory card and I am only using 8% of the card and now I can't write to it anymore?
Code:
Filesystem Size Used Avail Use% Mounted on
df -h returns this : /dev/sdd1
1.9G 136M 1.8G 8% /media/disk-2
This isn't the first time this has happened either. Just the last couple times I didn't really care enough to pursue it. But now I am trying to load a card for my daughters digital photo frame and I can't because now all of a sudden I can no longer write to the drive? The exact error message I get is: "Could not write to /media/disk/image.jpg" and when I try to create a new folder, I get a disk full error message? How in the heck is this possible when I am only using 136MB of 2GB of capacity?

I really enjoy using VIM to write python, but I recently tried to use it to write some essays for school. Are there any configurations that I could change in order to make writing longer essays easier using VIM? For instance, a way to be able to just jump one line (on the computer screen) down when I press the K key instead of jumping to the next paragraph?
