[PATCH libnbd v2 0/2] Implement systemd socket activation.
v1 was posted here: https://www.redhat.com/archives/libguestfs/2019-September/thread.html#00337 v2: - Drop the first patch. - Hopefully fix the multiple issues with fork-safety and general behaviour on error paths. Note this requires execvpe for which there seems to be no equivalent on FreeBSD, except some kind of tedious path parsing (but can we assign to environ?) Rich.
