May, 20th in the opensuse packaging mailing list, Michal Marek posted the following :

We have a firebird (the opensource SQL database) package in the server:database
buildservice project
(https://build.opensuse.org/package/show?package=firebird&project=server%3Adatabase).
Unfortunately, this package isn't maintained since some time, which is a pity, because the
server:database repository is offered as a community repository in YaST and is advertised
as the "Latest updates for database software including Firebird and MySQL".

Since I helped Mandriva to do their packages for Firebird, I jumped and with Michal, we
made things happen
Users of Opensuse 10.0,10.1,10.3 and future 11.0 but also SLE 10 can now just use the
server:database repository and get Firebird 2.0.4
As soon as the Firebird Project will publish Firebird 2.1.1, packages will be there too.
