Package: util-vserver
Version: 0.30.210-2
Severity: important
The init script executes a call to
setattr --barrier
for every entry $CURRENT in /etc/vservers, even if there exists no
/etc/vservers/$CURRENT/vdir, because e.g. $CURRENT is a file.
Files that may exist in /etc/vservers are e.g.
newvserver-vars (from vserver-debiantools)
*.conf (legacy config files, although I never used them)
The result of setting barrier on / are error messages like
# vserver-stat
chdir(): Permission denied
vserver myvserver start
access("/proc/uptime"): Permission denied
I fixed this by checking the existance of the directory before calling
setattr:

vdiractual=`readlink -f /etc/vservers/$vserver/vdir`

+ [ -d "$vdiractual" ] && setattr --barrier $vdiractual/..
done
# Then start up vservers with $MARK if $AUTO is set to start
# things
Perhaps a pre/post upgrade script should be added to fix updates from
problematic versions.
The command to be executed to fix the permissions is
setattr --~barrier /
