Is there an easier way to chroot than bind-mounting?

Question

Most of the time I use chroot to rescue an existing installation from usb.

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/

Is there an easy way already implemented in a standard Ubuntu install?

Answer 1

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
