Installing it **and** using the mentioned `grub-install` command to install it on the `/boot` partition over the previous version (2.02-2+sparc64.3) breaks booting with GRUB2:

Yes, this is something I don't have any control over. The grub2 package will break every time on sparc64 until GRUB 2.04 has been released with hopefully
all of Eric's patches merged.

I see.

Alternatively, you can try to convince Debian's GRUB maintainers (CC'ed) that
they will merge my patch from #854568 [1].

If they couldn't be convinced by you despite all your hard work on Debian Ports, not even for the experimental suite, why should they bother about me? :-)

But if someone cares: GRUB2 (w/those patches) allows network booting for sparc64 w/modern (aka huge) kernels and initram file systems - something that wasn't working properly (if at all) for a long time on sparc64.

Though the selection of per MAC/IP address configuration files during startup as of now is in fact not on par with other network capable boot loaders like pxelinux or yaboot, one can still script together a somewhat similar method (see [1]).

In addition it works on every sparc64 (Sun-4u, Sun-4v) machine I've tested so far.

Hence I consider it a must have for sparc64. And my machines see things the same way. :-)
