Can someone explain the following please?
In order for Webmin to run, it needs /var/run/webmin, as the following
extract from webmin.service shows:
[Service]
Environment="PERLLIB=/usr/libexec/webmin" ExecStart=/usr/libexec/webmin/miniserv.pl /etc/webmin/miniserv.conf ExecStop=/bin/kill $MAINPID
ExecReload=/bin/kill -HUP $MAINPID
PIDFile=/var/run/webmin/miniserv.pid
Type=forking
Restart=always
RestartSec=2s
TimeoutSec=15s
TimeoutStopSec=300s

So I create it, and all is good. However, it does not survive over
(re)boot, and I can't see why it should be deleted on shutdown, so I
have to re-create it on startup.

That's interesting about /run - didn't realise it's temporary nature. webmin.conf does not exist in my /usr/lib/tmpfiles.d/
/etc/tmpfiles.d/ is empty
I've created webmin.conf as per your cat output, and I'll check after
the next reboot.
Thanks.

/etc/tmpfiles.d/ is intended for temp file creation for packages from places other then Mageia, or as a place to override settings used by Mageia packages. It's empty unless you choose to create something there.

Did you install webmin from Mageia?
# rpm -q webmin
webmin-2.013-1.mga9
# rpm -ql webmin|grep tmpfiles
/usr/lib/tmpfiles.d/webmin.conf

Yes, I thought about that

Did you install webmin from Mageia?

No, from the webmin site and I always update from within webmin itself

# rpm -q webmin
webmin-2.013-1.mga9

webmin-2.111-1

# rpm -ql webmin|grep tmpfiles
/usr/lib/tmpfiles.d/webmin.conf

rpm -ql webmin|grep tmpfiles
Empty

Thanks for all your comments.

Ok. That explains why the tmpfiles.d file was not included. I don't know what if any other Mageia customizations are included in the Mageia version.

While the version from webmin is likely to contain some fixes and features not yet in the Mageia version, it's also likely to have some incorrect paths etc., and the Mageia version is tested, at least for basic functionality.
