Are you planning to push all your enhancements to upstream? Red Hat QE is using unionmount-testsuite to test overlayfs :) But it's downloaded from David's repo[1], which hasn't been updated for two years.

I'd like to see either porting all the tests from external repositories to fstests or keeping them separate as they're two independent testsuites. I'm reluctant to make fstests rely on an external testsuite and make fstests a wrapper of it. I think it's easier to maintain for both projects, and things are simpler this way and well self-contained. > - How does xfstests community feel about including python sources in the > xfstests repository? I think it's OK to include python sources if it's really needed. But we tend to not add more dependencies to fstests, if we have better choice, e.g. use perl instead. There's only one python script right now, tools/sort-group, but it's not used by the tests.
