chroot and dev, proc, sys

chroot is a great tool to rescue systems. But a limitation is that /dev, /sys and /proc are not mounted by default but needed for many tasks. This can be done by using mount –bind on the host. Here an example how to get a functional chroot:

mount --bind /proc /target/proc
mount --bind /dev /target/dev
mount --bind /sys /target/sys
chroot /target
