Script to enter Chroot Environment

kz_chopper · 02-04-2007, 03:28 PM

I created this file, chroot.sh to enter the chroot environment after a reboot. I saved it as root to / (You will need to change the mount command to reflect your system)

Code:

#!/bin/sh
# Enter the chroot environment
export LFS=/mnt/lfs
mount -t ext3 /dev/hda4 $LFS
mount --bind /dev $LFS/dev
mount -vt devpts devpts $LFS/dev/pts
mount -vt tmpfs shm $LFS/dev/shm
mount -vt proc proc $LFS/proc
mount -vt sysfs sysfs $LFS/sys
chroot "$LFS" /tools/bin/env -i \
    HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
    PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin \
    /tools/bin/bash --login +h

Then...

Code:

chmod u+x chroot.sh

To run...

Code:

./chroot.sh

And after entering chroot, don't forget to populate /dev (common cause of errors ...)

Me thinks its bedtime for you... If you actually LOOK at the script above you will see

"mount --bind /dev $LFS/dev" BEFORE chrooting.

Yep, you're right, should go to bed !!! I skipped this line !

Sometimes I should just shut up ...

After export and before mount, you need to make the directory $LFS.
