reason is: we want to verify the validity of the configuration.
if you configure an outdate peer handler (and use our heartbeat plugin
implementation dopd), you must have the permissions set like that,
otherwise the configuration won't work as expected.
we probably should add "--check-perms" to both drbdmeta and drbdsetup,
and let drbdadm _call_ them via exec, instead of iterating over $PATH
and I think it should not exit(10) if stat does not work, anyways,
since the other thing is a warning only, too.
