Description Jan Pokorný 2015-11-27 15:08:13 EST
Based on batch clufter testing, I've discovered that there is
an anti-pattern in netfs.sh agent, specifically in populate_defaults
function as it defeats the purpose of separating code and data values.
The latter should definitely go to metadata.  Amongst others, it has
an advantage of the value being easy to extract (to the benefit of
configuration management).

Optimal way to handle this is to specify the particular default
as a separate variable ("constant") in the script and refer to
it from within the metadata snippet to be emitted upon "meta-data"
request -- this is what heartbeat agents usually do.

I am intentionally leaving this bug with possibly a broader scope
as when solving this bug, it would make sense to check the other
rgmanager agents as well for the same anti-patterns...

Moved fstype default to metadata and verified that it's still working.

This bug was accidentally moved from POST to MODIFIED via an error in automation, please see mmccune@redhat.com with any questions

I have verified that the behaviour of netfs resource agent remains unchanged
after the patch in resource-agents-3.9.5-43
