See the issue?
Your dock.service, if run, would power-up and then immediately power-down the
dock.
Indeed. Does that mean I need separate dock-up and dock-down services?
I suppose. But, I can't say that there is a way to start a service went the
auto-unmount occurs.
Also, the .service is not being invoked by the .mount (I shouldn't have
to start it manually), presumably because the .automount isn't running.
I modified my aux.mount unit to be
[Unit]
Description=nfs mount aux
Wants=dock.service
[Mount]
What=[2001:b030:112f::19]:/volume1/aux
Where=/aux
Options=rw,noauto,soft,fg,x-systemd.mount-timeout=30
Type=nfs4
[Install]
WantedBy=multi-user.target
It then rebooted and.....
[egreshko@f33k ~]$ ll /var/tmp/auto/
total 0
-rw-r--r--. 1 root root 0 Mar 14 07:26 start
-rw-r--r--. 1 root root 0 Mar 14 07:26 stop
I then waited until it unmounted and accessed the share.
[egreshko@f33k ~]$ ll /var/tmp/auto/
total 0
-rw-r--r--. 1 root root 0 Mar 14 07:33 start
-rw-r--r--. 1 root root 0 Mar 14 07:33 stop
So, it is working as expected for me.
You may wish to try "crawling" first?
BTW, is there a recommended way to re-run this kind of test cleanly,
without having to reboot the system, e.g. after modifying one the
various unit files? I know about systemd daemon-reload but that doesn't
seem to be enough.
I used "systemd daemon-reload" in this test without a problem.
