Broken on illumos?

Trying to track down some caching problems with navidrome navidrome/navidrome#1048
and found that pulling down master and running "go test" fails:

That weird truncation of "aaaaaa" is exactly what we're seeing with navidrome

Relevant to #31

I wonder whether Illumos' file system file name limits are related? https://illumos.org/man/2/intro

[whorfin]

I am not sure which limits you are referring to
When godirwalk.Walk() was replaced with filepath.WalkDir() in navidrome , all of the unwanted filename truncation disappeared and cross-platform functionality was enabled.
