Adding those recipes for partman-auto will resolve the issue.
Should we add additional recipes or better modify the existing sparc recipe?
However, we should probably add a warning like we had for SILO which reminds users they have to add a bios_grub partition on a GPT machine:https://anonscm.debian.org/git/d-i/attic/silo-installer.git/tree/check.d/silo_checkDoes any of the other architectures which use GRUB require a bios_grub partition?
The "default" recipes use a bios_grub partition (see e.g. [1]). It's 1 MiB in size, but I expect that when partitioned on a gpt capable system this will result in 1 MiB space at the beginning of the disk and a 1 MiB partition after it. I assume this is created automatically on gpt capable systems, because of:
```
$iflabel{ gpt }
```
I don't know if this is required for GRUB2 on i386/amd64 though, but
maybe yes, so GRUB2 doesn't touch the 1 MiB space at the beginning.
