imho it does not make sense. I have many guests on /vserver
filesystem, which contribute to the overall system usage.

"du" from guest:
  # du -s -k -x /
12035668        /

"du" from host:
# du -s -k -x /vservers/vs1-web/
12035688        /vservers/vs1-web/

That is the same, which I consider as a solid indication
of correct function (although I agree it is not proof).

On the other side, there are big differences between "du"
and "df" on guest:

# df /
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/root             20971520   2581584  17324976  13% /
# du -s -k -x /
12035668        /

Again, it is not 100% proof that df is wrong, but when
I check /root in guest and count files manually (about
10 of them, each ~300MB, they make together more than 3GB.
So the whole root filesystem can not take less than that...
