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
