[Pkg-utopia-maintainers] Bug#1137419: cockpit-machines depends on libvirt-daemon-system which is not available on 32bit architectures anymore due to qemu dropped support for 32bit hosts

Hello Michael,

sorry for the delay! Some national/personal holidays came in between.

I suppose this is related to

https://salsa.debian.org/libvirt-team/libvirt/-/commit/f7c3ccddabded4b5919f0f39fcb1b43d4290366b#line_58ef006ab_A810

But I don't understand this. I get that libvirt-daemon-driver-qemu
was dropped, but libvirt can manage more than just QEMU, e.g. also containers
with LXC. That should still work on 32 bit machines. So why dropping
libvirt-daemon-system entirely, as opposed to just reducing its dependency to
libvirt-daemon-driver-qemu (as the patch also did)?

This is unrelated to cockpit-machines, but relevant for libvirt users.

I see:

https://ci.debian.net/packages/c/cockpit-machines/testing/i386/
https://ci.debian.net/packages/c/cockpit-machines/testing/i386/71625328/

At least it doesn't seem to block libvirt migration:

  https://qa.debian.org/excuses.php?package=libvirt

In theory it should, not sure why .. it's blocked on gnome-boxes rather.

Hmm, c-machines is Architecture: all. Conceptually, building on just the
supported architectures is right, but it'd have to become arch: any then and
that's difficult because reasons (esbuild yadayada).

I'll make the dependency architecture specific as a quick fix to unblock
migration.

Thanks,

Martin
