[arch-general] About tty

[Philippe Delavalade]

Hi list.

I'm new with archlinux and especially systemd. I'm using linux since around
twenty years, so i'm not realy newbie but...

I have many questions but I'll ask one by one.

I read wiki about systemctl and I'm not sure to have understood
everything :-( 

For instance, to have a daemon at boottime, I have tried :
systemctl enable --now ...
It seems to be OK with ntp, fcron and NetworkManager.

But with mariadb I obtain a failure.

Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xeu mariadb.service" for details.

I tried
systemctl status mariadb
and obtained
× mariadb.service - MariaDB 10.6.4 database server

Those messages don't help me.

Can someone tell me more ?

Regards.
