It=E2=80=99s really great that you=E2=80=99ve been looking at this! If I c= an be of any help, of if you feel desperate ;-), please don=E2=80=99t hesitate to ping m= e on IRC. > Also note that Hurd now seems to have some quite recent git tags, > which are also used by Debian, so we can expect less random commit > combinations not working. The good news is that Samuel Thibault is now officially a (actually: the) Hurd maintainer, which means they should be able to get upload permission to ftp.gnu.org=E2=80=94a step in the right direction. > Should we consider these blockers for a core-updates merge? Should we > somehow stop supporting the first use-case? In the past, I=E2=80=99d use =E2=80=98etc/release-manifest.scm=E2=80=99 as = a way to check for merge (or release) blockers. When it comes to cross-compilation, we must be able to cross-compile the bootstrap tarballs, as in: ./pre-inst-env guix build bootstrap-tarballs \ --target=3Daarch64-linux-gnu -n That works well on =E2=80=98core-updates=E2=80=99 so far, except for i586-p= c-gnu. Thanks, Ludo=E2=80=99.
