Hi Adam and Johannes,

I tried using mmdebstrap for loong64 and that didn't go well. The
failure has multiple layers. I actually found the first layer last.

1. arch-test has no clue about loong64 and therefore mmdebstrap goes
   investigate what's the problem with it.

2. mmdebstrap figures that it has no clue what the qemu arch name for
   loong64 is. Please extend the mapping to loong64 => 'loongarch64'.

3. Then, mmdebstrap looks up qemu-loongarch64 using update-binfmts
   --display, but since Debian trixie, qemu-user-binfmt no longer
   installs its files to /usr/share/binfmts and no longer supports
   update-binfmts. They are only installed to /usr/lib/binfmt.d now.

Maybe the loong people can supply patches here?

Helmut
