Comment 27 for bug 303232

Dave, on the use of multiple sources.list entries:
Note that http://mojo.handhelds.org/hasty-armv6el-vfp/ only cascades deb-src entries. We discussed the idea of another archive, but this is quite a stretch to setup and maintain; of course you need infrastructure (disk space, buildds, bandwidth etc.), but also it needs maintenance (watching the builds), separate QA, and is quite confusing to end users. Ideally, you also want a mechanism to prevent mismatches of packages on target systems. The way to do this would be to add subarch support to dpkg/apt and enforce subarch equality when installing binary packages (the subarch of the binary package needs to match the subarch of the system).

[Note that the mojo folks "abused" the "arm" port; AFAIK they built binaries for EABI using "arm" as Debian architecture, so they offer .debs which dpkg will allow to install on a Debian arm install despite being another ABI. That was the easiest path to get these interesting archives, but it breaks ABI, so not something to do officially IMO. What's possible however is to rebuild the armel archive with higher CPU requirements, keeping the same ABI.]
