The sysfs content was also copied over from the VM but only those files which are accessed in the test are stored in the repo.

This unfortunately introduces symbolic link loops. They are fine in sysfs, but we always had issues with them when running distcheck and similar.
I tried it now and did not reproduce the exact issue, but it still is not nice (global -u complains, some programs might just end up in an infinite loop). Historically we replicated "just enough" to use it in tests, but not so much that it would introduce loops. I would prefer if it stayed that way.
Yeah, I remember us fixing this, but I don't recall all the details. I'll switch to files. Michal
