Mageia 1 is there : http://blog.mageia.org/en/
It is a community driven project and a Firebird friendly distribution with Firebird2.5.0, PHP, PHP-pdo, Perl, Ruby drivers, Rails adapter, Flamerobin, and Pythondrivers (kinterbasdb and firebirdsql).
I'm really happy to have now Mageia on my computer, and being one of thepackagers.
For people wanting to use Firebird under Gnu/Linux, Mageia can be a reallygood choice.
The community is active, and in next months will decide what will be thefuture. Like Firebird, Mageia organisation is community-driven; no commercialmanagement can dictate the path Mageia will take.
Download it,try it !
PS
Some friends of mine created Hupstream a company providing commercialservices (like IBphoenix for Firebird) with or around Mageia software, tools or project .
So you can imagine Firebird under Mageia with professional support withIBPhoenix and Hupstream if you want !
