Re: [Bug 696007] Re: write_buffer variable in my*.cnf templates is obsolete
The my-*.cnf files should be removed completely, they're old and quite
wrong in many ways.
Their continued existence just keeps causing trouble.

The Debian/Ubuntu packages already contain a good start for a baseline
config, this could be put in the Maria repo.

Ups! You are absolutely right. It's my fault. Sorry about that!

I partly agree with you. They are not contemporary any more. But I would
not remove but refresh them.

Many MySQL/MariaDB user take them as a starting point and when we remove
them they get even worse set-ups than with the existing templates.

What settings are "quite wrong"? So we should fix these...

IMHO ideally we should have a small, medium and large (possibly with a
recommendation what small, medium and large means) config for each
storage engine.
So we end up with 3 x 4 = 12 different config files OR we have a small,
medium and large config file and have a section per storage engine in it.

Regards,
Oli

Please see the answer I gave before, and my solution. I did the
homework.
