Re: MariaDB won't start after updating Fedora 26 to Fedora 27


Thanks Reindl.

I want to do it the way Fedora should be doing by default as there are a few servers, and I don't want to deviate from being able to update them all just using "dnf ..." in future - it's worked fine that way for years.
Actually I have one still on F26, and just bounced it to see that the dir in question is recreated OK. So, if tmpfiles.d is the way it's being done, what would I look for on *that* system to see why it broke on F27 please? I'm not a db guy at all, I just need to get the db up each boot without manual intervention, or worse a custom dir creation script which may break in the future.

https://www.freedesktop.org/software/systemd/man/tmpfiles.d.html or make 
a proper unit because the pid-file is not needed at all as well as
