IMHO the only thing which is reasonable here would be something simple
with posix semantics, which is unlikely to change on-disk format anytime
soon. So symlinks are working (which appears to be used by atomic /
ostree), which is something vfat can't support.
ext2 looks like a good pick here. Simple, posix, no journal replay
issues, and drivers for non-linux systems are relatively widespread.
