I want systemd on
mount /mnt/test to automatically call a program (in real life
cryptsetup to unlock the underlying device, for testing here
echo) before the file system is mounted and after it is unmounted.
[Unit] Description=stickbak encryption Before=mnt-test.mount StopWhenUnneeded=true [Service] Type=oneshot ExecStart=/bin/echo Unlock device. RemainAfterExit=true ExecStop=/bin/echo Lock device. [Install] RequiredBy=mnt-test.mount
/dev/$DEVICE /mnt/test auto noauto 0 0
this works (after daemon reload and enabling the service) for
systemctl start mnt-test.mount and respectively
systemctl stop mnt-test.mount (as root).
mount /mnt/test, however,
systemctl status mnt-test.mount stickbak-encryption shows the latter service being
inactive (dead), while the former is
How can I (or can I not?) set up a dependency that is honoured when
/bin/mount is called as well? The status of the mount unit shows that
mount /mnt/test seems to be translated to
ExecMount=/bin/mount /dev/$DEVICE /mnt/test -t auto -o noauto, so apparently systemd gets notified.
