Is that normal practice? Sorry, sounds like a > mess to me. Debian/sh4 is not a release target, so it's not being shipped and there is no warranty anyway. I also don't have the possibility to rebuild the whole archive in a separate project. There is only unstable. If am doing a complete rebuild now, I will be busy for the next weeks or months (there are new packages coming in every day) looking at issues because there might be a lot of failing packages, also for other reasons. It's simply not practical from my perspective. I'm doing this as a hobby, not as a full time job, so I can't take care of all issues all-day long. And, finally, the buildd capacity is limited on sh4. If this was POWER or SPARC, we would have plenty of resources for a complete rebuild.
