How to share a directory, such as /home, among multiple vserver guests.
Assumptions
Suppose you have multiple vserver guests at locations such as /var/lib/vservers/<guest>/.
You would like to share a directory, such as /srv/common/home, among multiple guests.
Each guest will be able to write to the directory.
Command
The following command will mount this directory for all guests:
$ for guest in /var/lib/vservers/*; do mount --bind /srv/common/home ${guest}/home; done
fstab
Alternatively, you may add an entry similar to the below one in /etc/vservers/<guest>/fstab:
/srv/common/home /home none bind 0 0
