>From within the VPS:

# mount
simfs on / type simfs (rw)
proc on /proc type proc (rw,nodiratime)
simfs on /.dev type simfs (rw)
tmpfs on /dev type tmpfs (rw)

>From the Host:

# mount
/dev/sda2 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda1 on /boot type ext3 (rw)
none on /dev/shm type tmpfs (rw)
/dev/sda5 on /vz type ext3 (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

I'm confuses where I would make the changes you recommended and how.  Thanks
