thanks, following your other post:
I come out with a service to be run before the lxd.daemon:
[Unit]
Description=Setup foo
Before=snap.lxd.daemon.service
[Service]
Type=oneshot
ExecStart=/opt/foo/setup-foo.sh
RemainAfterExit=true
ExecStop=/opt/foo/teardown-foo.sh
StandardOutput=journal
[Install]
WantedBy=multi-user.target
if setup-foo.sh succeeded , snap.lxd.daemon.service got started, good, but if setup-foo.sh failed , snap.lxd.daemon.service got started as well, is this how ‘Before’ directive works? thanks
