Another problem has arisen. debian-ports has no support for testing migrations. This could prevent Emdebian Grip creating a testing distribution for SH4 that would be suitable for a stable release. What happens is that the packages that *should* remain in testing and go into freeze, will be replaced by subsequent uploads to unstable which are *not* to be released. Files literally disappear or do not exist in time before the equivalent Debian package has migrated. If SH4 is to be a release architecture for Emdebian Grip, this will have to be fixed. The only real way to do that is to get SH4 into ftp.debian.org and subject to the usual "Britney" rules for testing migration as a release architecture for Debian. Emdebian Grip does not have the manpower or resources to duplicate the Debian release team and their testing migration coordination workload - partly because that would mean delaying testing migrations on behalf of SH4. We cannot simply assume that package "foo" migrates into testing on SH4 in Emdebian when Debian does not have a testing package (even in -ports) - there is no guarantee that the appropriate version has yet been built for SH4 because testing migrations do not wait for SH4 to be up to date (it isn't a release architecture). This will have to be fixed before any packages are frozen for the Debian 6.0 "squeeze" release. The only other way is for someone else to manage SH4 testing migrations in a "best-effort" process in their own repository, using the scripts in emdebian-grip-server - or on debian-ports. This level of work-duplication is not attractive, the best approach would be to get SH4 into the list of architectures deemed suitable for release with Squeeze. It turns out that the links between Emdebian and Debian are deeper than may first appear - testing and freeze processes are tightly integrated. Releasing SH4 in Emdebian Grip is not shortcut to getting SH4 accepted as a release architecture for Debian - indeed, unless -ports can support testing migrations, support in Emdebian must follow support in Debian, not vice versa. -- Neil Williams ============= http://www.data-freedom.org/ http://www.nosoftwarepatents.com/ http://www.linux.codehelp.co.uk/
