Dear Maintainer,
my Debian client still has this bug.
it mounts reularly at boot, but it hangs at the shutdown.

my fstab has NFS entries similar to the following:

	192.168.x.xyz:/srv/nfs4/smtgh /media/smtgh	nfs	defaults,rw,x-systemd.automount,x-systemd.device-timeout=3	0	0

the output of systemctl list-dependencies media-smtgh.mount is:
	media-smtgh.mount
	● ├─-.mount
	● ├─system.slice
	● └─network-online.target

the output of systemctl cat media-smtgh.mount is:
	# /run/systemd/generator/media-smtgh.mount
	# Automatically generated by systemd-fstab-generator

	[Unit]
	SourcePath=/etc/fstab
