This may actually be an error.  This new info was on a linked file 
(using templates).  I tried on a VPS that has broken the link and found 
this:

# ls -ali /vz/private/101/root/bin/ls
245325878 -rwxr-xr-x    1 root     root        67700 Sep 29 11:42 
/vz/private/101/root/bin/ls
# ls -ali /vz/root/101/bin/ls
245325878 -rwxr-xr-x    1 root     root        67700 Sep 29 11:42 
/vz/root/101/bin/ls

Or - the third thought is that we are better off not using the CoW/vzfs 
part of Virtuozzo at all and OpenVZ is a more scalable alternative to 
Virtuozzo.
