[debian-mysql] Bug#1032407: Cannot start mariadb-server unless manually mkdir -p /var/lib/mysql

[MichaIng]

Who do you mean? Should be reported here by OP who faced the issue: 
https://github.com/puppetlabs/puppetlabs-mysql/issues

Only the Puppet MySQL module developers will know whether they need 
plain text logging for some specific reason and how to hence address 
this best.

Bookworm (and hence this change) is in "testing" now, in hard freeze 
stage of the upcoming Debian release. So a pretty perfect time for 
testing and reporting issues as of changes like this to software 
developers to update their software. And optionally to make it more 
compatible in the same turn by not relying on the existence of 
explicitly configured directories ;).
