[Vserver] vhashify on Debian / CoW links not breaking on chmod/chown?

Hello all,

I started playing with vserver unification recently and I'd like to
share my two observations:

 - under Debian (sarge at least) you cannot use the supplied beecrypt2
packages as they have a slightly different API (changes are subtle
enough that util-vserver will compile but hashcalc will die with a
segmentation fault). Use beecrypt4:
http://prdownloads.sourceforge.net/beecrypt/beecrypt-4.0.0.tar.gz?download

 - If I modify a file's contents the CoW link is broken properly but
after a chmod or chown the link is not broken and I get -EPERM (as the
files are marked immutable) - is this expected behaviour? In such a
situation the links aren't exactly CoW...

Best regards,
 Grzegorz Nosek
