generating fstab

Prev		Next

I want to modify some options in my fstab (umask parameter for vfat disks, for instance). It seems that fstab is generated at boot time by linuxlive scripts. Putting my modified fstab in rootcopy doesn't work (and is not a good solution imo). So, who can I change the way fstab is generated ? Where to add the tweaked parameters ?

as markds wrote, it is located in initrd.gz.

copy initrd.gz (e.g. in /tmp
gunzip /tmp/initrd.gz
mkdir /mnt/initrd
mount -o loop /tmp/initrd /mnt/initrd
cd to /mnt/initrd and change liblinuxlive as needed
umount /mnt/initrd
cd /tmp && gzip —best initrd
copy changed initrd back to cd/usb
remember that liblinuxlive gets copied from initrd into the system during boot, thus changing /usr/lib/liblinuxlive is senseless.

Great !

Many thanks for those informations, it worked just fine. If anyone is interested :

I couldn't mount initrd (error message -> mount: could not find any free loop device) so I did :
```
# mknod -m 0600 /dev/loop255 b 7 255
# mount -o loop=/dev/loop255 /tmp/initrd /mnt/loop
```
The changes I made is because it bugs me to have all files/directories in vfat drive to be chmod 777 and thus appear green with ls —color. So, on line 276 of liblinuxlive file I removed "umask=0" and replaced by "fmask=0133,dmask=0022"
I had to close the shell where I did the "mount" because I couldn't "umount" (error message -> unmount loop device is busy). A "lsof /mnt/loop" showed me that zsh used the file. I closed the shell and did the "umount" from an other shell.
