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:

Does 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.
