several utilities (like df) use the mount entries (/etc/mtab)
for locating their devices/gathering information ...

for these utilities the fake entry is provided ...

if you use per vserver quota, you will also need a
special device to proxy the quota syscalls ...

depending on the release version of the vserver scripts,
some or all automatic mounts are removed if possible
(i.e. no other programms or mounts active)
