Hi,
the following works, but I doubt that it is a nice way to do it. I have
a generator that generates a number of service, and I want all of those
services automatically started at boot. I have:
$ sudo systemctl cat console-log-8.service
[sudo] password for mh on hover:
# /run/systemd/generator/console-log-8.service
# generated by console-log.generator
[Unit]
Description=page tty8
After=console-log.target
[Service]
...
[Install]
WantedBy=console-log.target
$ sudo systemctl cat console-log-9.service
# /run/systemd/generator/console-log-9.service
# generated by console-log.generator
[Unit]
Description=page tty9
After=console-log.target
[Service]
...
[Install]
WantedBy=console-log.target
$ sudo systemctl cat console-log.target
# /run/systemd/generator/console-log.target
# generated by console-log.generator
[Unit]
Description=Pull in all console-log units
After=multi-user.target
Wants=console-log-9-var-log-syslog-syslog.service
Wants=console-log-8-var-log-exim4-mainlog.service
[Install]
WantedBy=multi-user.target
$ sudo systemctl cat console-log-starter.service
# /etc/systemd/system/console-log-starter.service
[Unit]
Description=Start console-log.target at boot
After=multi-user.target
[Service]
Type=oneshot
ExecStart=/bin/systemctl start console-log.target
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target
$
The console-log-starter.service is the only persistent thing, all others
are generated (including the target since the target lists all generated
services). So I cannot enable them. The console-log-starter.service is
the first unit that I can actually enable.
When I search on the Internet I read that the generator should generate
"the Wanted" Symlinks itself, but the docs also say that the generator
can't write outside its target directories. And I don't have a clue
which symlinks I am supposed to generate in the generator. And in the
running system I don't see any symlinks regarding my units other than
the
/etc/systemd/system/multi-user.target.wants/console-log-starter.service
-> /etc/systemd/system/console-log-starter.service one that was
generated when I enabled the start service.
Am I supposed to
ln -s /etc/systemd/system/console-log-8.service
/etc/systemd/system/multi-user.target.wants/console-log-8.service and
ln -s /etc/systemd/system/console-log-9.service
/etc/systemd/system/multi-user.target.wants/console-log-9.service?
How am I supposed to do this correctly? Or is my entire approach wrong?
Greetings
Marc
