FWIW, on Debian guix 1.3.0 is currently at risk due to armhf and
i386/i686-linux missings builds due to test suite failures. It has been
hard to keep up with Guix in Debian, especially supporting "obscure"
platforms...

Though I'm guessing there may be reluctance to drop support for
i686-linux... I much more frequently encounter test suite failures when
building it, at least on Debian. It is surely less well supported than
x86_64-linux.

But dropping armhf and i386 at the moment looks ... helpful from a
Debian packaging perspective... :/

I'll try to package a git snapshot of guix and see if that fares any
better and hopefully find and fix issues before the next guix release!

live well,
