[Users] [PATCH] vzctl - vps_save_config

[Philipp Wehrheim]

Hey,

the attached patch fixes an issue where vzctl overwrites the symlink
to CTs config.

In my setup the CT config is stored in /vz/ve/<CTID>/<CTID>.conf
and linked back to /etc/vz/conf/<CTID>.conf .If I make changes to the
CTs config via "vzctl set ..." the link is overwritten by vzctl on writeback.

Please consider applying.

cheers
