- Add the public key to authorized_keys instead of replacing the file.
- Use AF_INET6 when GSTFSD_BIND_HOST is an IPv6 address (binding ::1
crashed with the AF_INET server).
- Close idle client connections after 30 s.
Tests run the real daemon against a small fake guestfs module over a
socket; this also exercises the earlier sendall() fix.
- Hash the root password with a random SHA-512 salt instead of the fixed
"$6$kgPoiREy".
- Talk to gstfsd through one helper with a 120 s socket timeout; an
unreachable daemon or a bad reply is an error message, not a 500.
- gstfsd refuses to listen on a non-loopback address unless
GSTFSD_ALLOW_REMOTE=1: it is an unauthenticated root service.
- gstfsd: encode replies (sendall(str) raised TypeError on Python 3, so
the success path never worked) and use octal chmod modes.
- README: what gstfsd does and how to allow it on a remote compute.
