This is a very plausible explanation. However I wonder whether it should be
documented more clearly in the RA writers guide (or corresponding document).
The other thing is whether a group "hacluster" and a "chgrp hacluster
$HA_RSCTMP; chmod g+rwx $HA_RSCTMP" would be a good idea (assuming crmd is run
as hacluster:hacluster then).
The other thing would be messing with "setfacl -m u:hacluster:rwx $HA_RSCTMP"
