Bug#826512: [systemd] automount hangs after first unmount

Version: 230-2

Hi,

Recently (maybe after upgrade to systemd 230?), my automount settings
only work for the first mount request.

E.g., I have in fstab:

belette:/nas/musique /home/adrien/Musique    nfs   
defaults,users,noauto,x-systemd.automount,x-systemd.idle-timeout=10s   
0    0

The 10s setting is for debugging purpose, I usually use 10m.

# systemctl start home-adrien-Musique.automount
# journalctl -u home-adrien-Musique.automount -u
home-adrien-Musique.mount -f

home-adrien-Musique.automount.
juin 05 22:17:53 complexe systemd[1]: home-adrien-Musique.automount: Got
automount request for /home/adrien/Musique, triggered by 1084
(gvfs-udisks2-vo)

juin 05 22:17:53 complexe systemd[1]: Mounted /home/adrien/Musique.
juin 05 22:18:03 complexe systemd[1]: Unmounting /home/adrien/Musique...
juin 05 22:18:03 complexe systemd[1]: Unmounted /home/adrien/Musique.


After waiting for the unmount, I open another terminal, and try to 'll
/home/adrien/Musique'. The process is stalled and nothing shows up in
the log.

Starting the mount manually is working, so NFS seems out of the issue,
but I'm open for testing suggestions.
