Chroot
1. Create a mountpoint (skip for squashfs example)
Code:
mkdir squashfs-root
2. Mount /proc /sys /dev to chroot
Code:
mount -o bind /proc squashfs-root/proc/ mount -o bind /dev squashfs-root/dev/ mount -o bind /dev/pts squashfs-root/dev/pts/ mount -o bind /sys squashfs-root/sys
3. Copy resolv.conf to networking
Code:
cp /etc/resolv.conf /mount/point/etc/resolv.conf
4.Open bash in chroot
Code:
chroot /mount/point /bin/bash
5. Do what you have to do and then exit chroot
Code:
exit
6 Cleanup
Code:
umount squashfs-root/dev/pts/ umount squashfs-root/dev/ umount squashfs-root/sys umount squashfs-root/proc/
