When I chroot into another system I have to manually bind-mount proc, sys, dev and dev/pts by issuing for example

mount --bind /proc proc/

Now is there an easy way allready implemeted in a standard Ubuntu install? I am asking about the standard install because most of the time I use the chroot to rescue an existing installation from usb.

See the schroot package. Man Page

As an alternative, you can shorthand the bind mounting with:

for f in proc sys dev ; do mount --bind /$f /mnt/$f ; done

You could add references to the manual page and provide examples. – Lekensteyn Mar 28 '11 at 17:42
well... that's kindof why I asked about the standard Ubuntu install. Of course there exist tools that do that. But is it as simple as sudo apt-get install schroot && schroot /dest ? – turbo Mar 28 '11 at 17:54

@turbo in that case, no. One thing that can help save some typing though is rather than issue 3 separate bind mount commands, you can just do "for f in /sys /proc /dev ; do mount --bind $f /mnt/$f ; done" – psusi Mar 28 '11 at 19:16
yeah that's a good one. I knew and forgot about one line bash 'scripts'. I just seems kind of obvious from Ubuntu's point of view to include something like this in their rescue menu. – turbo Mar 28 '11 at 19:52

@turbo, @psusi --bind only mounts the specific named filesystem; it won't include pts or for that matter shm. However if you use mount --rbind it will work. – poolie Apr 12 '11 at 2:33
