Hi,
Can git's is_path_owned_by_current_uid() be made to check to see if the
filesystem is a network filesystem (9p, afs, ceph, cifs, nfs, maybe orange?)
before deciding that you're not allowed to do a command because your UID
doesn't match?
One way to do this would be to check the filesystem type returned by statfs:
statfs(".", {f_type=AFS_FS_MAGIC, ...
Alternatively, we could add a statx() attribute flag in the kernel to indicate
that the uid/gid is from a separate set of IDs (or fabricated entirely) and
cannot by directly compared against system IDs.
Thanks,
David
