init script for util-vserver does not properly mount cgroups hierarchy
The init script for util-vserver is not mounting the cgroups hierarchy (namely, only one of the elements of the hierarchy) properly because of line 61:
$__PKGLIBDIR/bash-wrapper ‘_generateCgroupOptions; test -n “$CGROUP_MNT” || exit 0; $_MKDIR -p “$CGROUP_MNT”; $_MOUNT -t cgroup -o “$CGROUP_SUBSYS” vserver “$CGROUP_MNT”’
The problem is that $CGROUP_SUBSYS is an array and needs to be rejoined into a comma-separated list for mount. This should be sufficient:
$__PKGLIBDIR/bash-wrapper ‘_generateCgroupOptions; test -n “$CGROUP_MNT” || exit 0; $_MKDIR -p “$CGROUP_MNT”; IFS=“,”; $_MOUNT -t cgroup -o “${CGROUP_SUBSYS[*]}” vserver “$CGROUP_MNT”’
If you really want I can provide a proper patch later. :p
