→Unmount script example
umount scripts could cause trouble and errors on VM start and might not be required if using the -n option on mount. [http://forum.openvz.org/index.php?t=msg&goto=37800&&srch=using+-n+and+no+umount+script#msg_37800 read forum post]
When mounting whitout <code>-n</code> option, <code>umount</code> script become required, but display errors,
because of recursivity of umount procedure initiated before by libvzctl.
Even if no option <code>-n</code> was specified at mount, and no <code>umount</code> script was run,
system file <code>/etc/mtab</code> could become wrong in the HN, causing trouble to commands like df.
