[debian-mysql] Bug#970045: galera-4: Use user "_galera" instead of "nobody" to run the daemon

[Otto Kekäläinen]

Source: galera-4
Version: 26.4.5-1
Severity: wishlist

Using nobody and nogroup is currently discouraged:
>The specified systemd service file declares a User= or Group= that references nobody or nogroup.
> This is discouraged, and systemd versions 246 and above will log a warning about this.

W systemd-service-file-uses-nobody-or-nogroup
lib/systemd/system/garb.service User=nobody
W systemd-service-file-uses-nobody-or-nogroup
lib/systemd/system/garbd.service User=nobody

According to https://www.debian.org/doc/debian-policy/ch-opersys.html#users-and-groups
it seems the proper solution would be to have a new user "_galera" for
this daemon instead.
