The way I'm splitting up tests is one first run with a basic xfs section
on a configuration file, with no external log, which pretty much runs all
tests but excludes all which require external or funky configurations.

A secondary pass then goes through these extra groups and then runs tests
only for the previously excluded groups but with their own respective
section. So for instance in this case I have:

[xfs]
....
[logdev_xfs]
...

Automatic detection if the requirements are met is fine, but this doesn't 
let me easily use say:

	./check -s logdev_xfs -g logdev

I see...

So for my case would one better goal be to just run check without the external
one and one with the external log?

  ./check -s xfs -g log
  ./check -s logdev_xfs -g log
