How to mount /proc and /dev and in chroot on Linux

I’m using a backtrack Linux to recover a broken Ubuntu Linux, to fix this disastrous situation I’m using the Ubuntu Linux through chroot after mounting my /dev/sda1, where my Linux resides with:

linux-recovery:~# mkdir /mnt/test1
linux-recovery:~# mount /dev/sda1 /mnt/test1
linux-recovery:~# chroot /mnt/test1
ubuntu:~#


I consequently needed to mount up the /proc and /dev partition inside the chroot environment.
Here is how I did it:

ubuntu:~# mount /proc
ubuntu:~# mount -a


Next I switched on on a different virtual console in the backtrack and to mount /dev issued the commands:

linux-recovery:~# mount --bind /dev /mnt/test1/dev


Now once again, I can use the apt-get inside the chroot to fix up the whole mess …

sudo mount /dev/sda1 /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc

Теперь перейдем в окружающую среду chroot:

sudo chroot /mnt
