[debian-mysql] Common mechanism for detecting which MySQL variant and version is installed

[Ondřej Surý]

Hi Lars,

as all packages depend on mysql-common, right? So we can include such
script into
the package and each *-server-core would then provide same magic file.

Also thinking in a long term - in theory we might be able to make
*-*-core-* packages coinstallable with each other, so perhaps we need to
think about this before crafting a solution. What do you think?

Cheers,
