→Make /etc/mtab a symlink to /proc/mounts
The container's root filesystem is mounted by the host system, not the guest — and therefore root fs will not appear in <code>/etc/mtab</code>. It will lead to a non-working <code>df</code> command. To fix, link /etc/mtab to /proc/mounts.
<pre>
rm -f /vz/private/7771001/etc/mtabln -s /proc/mounts /vz/private/7771001/etc/mtab
</pre>
After replacing <code>/etc/mtab</code> with a symlink to <code>/proc/mounts</code>, you will always have up-to-date information of what is mounted in <code>/etc/mtab</code>. You will, however, have an error on boot (in <code>/var/log/init.log</code>) that can be safely ignored: <code>* /etc/mtab is not updateable [ !! ]</code>
