Ok, after some hours, I managed to set up my first buildd (on i386 :( ). That was not so hard after all, but I would have loved a few more documentation.
Anyway, I plan to run a buildd on another sparc box, so I'll write some documentation at this moment.

Yesterday eveni^Wnight, I filled up the wanna-build database with all Debian source packages.

buildd

But... Doh! It seems it found its first FTBFS! What a lovely buildd!
