Hosting wanna-build on debian-ports would be awsome. You already
are expirienced in it, and it is good to have centralized
and better maintained place for this (as debian-ports is
already for about 10 ports).

Probably the hardest part is bootstraping repository
with essential packages. Are there any instruction
from which packages we should start, or wannt-build will
perform this automatically somehow?

Absolutly.

I can offer almost right now 2 fully loaded XP1000 exclusivly for buildd.
All boxes have essentially 21264 500MHz, 1GB RAM, 4x 9GB fast disk,
and Internet connection using IPv6. I can try putting them on IPv4
but this will be harder.
I am now waiting for delivering more RAM so I could put 2GB of RAM
in each and bigger ethernet switch, because I have now everything
filled in office. :)

I'm still fighting with IDE performance (XP1000 are known to have
problems with DMA on IDE), but it will be solved soon (about a week),
and actually isn't big deal, as main storage for buildd will be on SCSI.

(I have 3 more XP1000, but I'm using them for my own tasks,
kernel reboots, Xorg, experimental stuff, etc. One of them also do
not have harddrives and RAM, cause I put this resources into another ones.
And in the process I yeasterday trashed two XP1000 boxes :/
They were totally dead, fortunetly I took memory and storage,
so we can use it for something more usefull. ).

As of buildd, I already installed buildd and sbuild on one
of this machines, and it essentially works, but would
be better, if debian-ports can provide own buildd/sbuild/apt
repositories for this, as well setup instruction
(I was obviously using Debian's one).

I would also want to know if anybody else would need
to have administrative access to the buildd machine?
As i understand buildd user, unfortunetly can sude into root
(because it for example create LVM snapshots, mounts,
unmounts, deboostrap, etc.). So, what security
issues needs to be taken into consideration?

Me too. At least from time to time. (two time a week maybe).
Definietly more frequently for my own machines.
