Target any service instance when using "PartOf" in a systemd unit file
Greetings,
I am trying to configure a wildfly daemon to restart whenever postgresql
restarts (which happens sometimes due to Debian's unattended-upgrades).
I tried to solve this by putting "PartOf=postgresql.service" in
/etc/systemd/system/wildfly.service.
The problem is that postgresql.service can have multiple instances like
postgresql@14-main.service and postgresql@15-main.service, as a new
instance is created with each version upgrade. When this happens, the
main service postgresql.service actually isn't being restarted. Is it
possible to configure wildfly to be restarted when ANY of the postgresql
instances restart?
Cheers!
Jonathan
