Description:
Box64 lets you run x86_64 Linux programs (such as games) on non-x86_64 Linux
systems, like ARM (host system needs to be 64-bit little-endian).

This needs access to x86_64 libraries to actually be useful. The easiest way to get those is to

dnf --forcearch=x86_64 --installroot=/path/to/x64root install <packages...>

and then set BOX64_LD_LIBRARY_PATH=/path/to/x64root before running box64.

Taking this review.

Spec review:

> Requires(post): %{_sbindir}/update-alternatives
> Requires(postun): %{_sbindir}/update-alternatives

Why are we using alternatives instead of Provides+Conflicts and "RemovePathPostfixes" stanzas?

Example of this: https://code.opensuse.org/package/pagure/blob/master/f/pagure.spec#_218-238
Comment 4 Davide Cavalca 2023-06-25 09:33:14 UTC 
Because I figured may want to have the generic aarch64 version and the platform specific one installed concurrently to compare and contrast (not on Apple Silicon, as you'll need the -asahi one for 16k, but on other platforms).
