Shared network filesystems I have them mounted on the host filesystem.
This happens before util-vserver starts and you use the _netdev option
in the hosts's fstab to ensure the filesystem is mounted after network .
In the guest's config fstab I use -o bind to have the already mounted
shared filesystems bind-mounted on the guest
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
/shared/home /home none bind,rw 0 0
/shared/vhosts.d /etc/apache2/vhosts.d none bind 0 0
