As far as I understand, the usual way to port debian is to setup a build system and then proceed natively building all packages. I don't think that you will be successful building squeeze from scratch for powerpcspe. Some packages need patches to properly build on powerpcspe (i think that even includes libc6). Those packages are not even in 'unstable' but in 'unreleased'. By the way I'm going to use debian-powerpcspe for an embedded system, too. Already set up a pretty usable build systems on a p2020rdb, based on debian-ports sid+unreleased. Luckily we have quite some time until this has to be stable, so having to use unstable is no show-stopper for now. Also debian-unstable might as well be more complete and stable than other options. Hopefully, now that squeeze is released, powerpcspe related patches can migrate into sid, and hopefully we'll finally see debian 'testing' build for powerpcspe (that would already qualify as 'stable' for me). The main people currently working for debian-powerpc are (afaik): Sebastian Andrzej Siewior <bigeasy@linutronix.de>, "Moffett, Kyle D" <Kyle.D.Moffett@boeing.com> I usually CC them when posting about powerpcspe-specific issues. Maybe they can shed some light on how things are stabilizing, and where help is needed (i'd be able to spend a few days per month on ppcspe). You know, the best way to make it more stable is to use it, report problems, and contribute patches :) cheers, David -- GnuPG public key: http://user.cs.tu-berlin.de/~dvdkhlng/dk.gpg Fingerprint: B17A DC95 D293 657B 4205 D016 7DEF 5323 C174 7D40
