Shitty Systemd Unit Files

Again I will rant on PostgreSQL a bit - and systemd. I dislike systemd, especially when something like postgres fails to start, systemd writes “run these shitty commands which shows nothing useful” basically saying fuck you.

Like here - I got “Examine the log output.”. Well, the fucking systemd is log output. I had to run postgres by manually. Fortunately I think it loaded configuration just fine even with bare command, so wasn’t that painful except having to switch to postgres user with explicit shell.

rapthalia:/etc # su -l postgres -s /bin/bash
postgres@rapthalia:~> postgres
2022-02-11 00:49:45.508 CET   [20205]FATAL:  database files are incompatible with server

Why are we here?
Just to suffer?
Every night,
I can feel my SysVinit and OpenRC
even my runits
The service managers I’ve lost…
the comfort I lost…
won’t stop hurting
It’s like they are still there.
You feel it too, don’t you?

P.S. Postgres, why -h can’t be help, but hostname? Why can’t we have nice things?
