Re: Installation tests with GRUB on GPT disks

Ok, I just successfully tested this change.
Two questions left:
1. Can you test whether we can drop the /boot partition on Sun
partition tables?
I actually don't remember if I tested such a configuration. At least
d-i/grub-installer should support this now. I'll check that on my T5220
and report back.
Just a thought:
Could it happen that - depending on the size of the root FS and the
amount of packages installed - the GRUB image gets installed so far away
from the start of a disk - it usually gets installed at the end of an
installation - that older machines with older OBP versions could have
problems to access it via block lists? Are there any such limits?
If yes, a separate smaller partition for "/boot" might be required in
such a case.
2. Now that we can use GRUB, what about updating the default
partitioning scheme? Maybe one that is inspired by the layout
used on ppc64el:

You want to add "$defaultignore{ }" for the "/boot" partition, so it's
only active by default for installations using LVM? Maybe there are also
other use cases for a separate "/boot" partition than LVM. Such a change
would make it harder for people with those other use cases then.
3. GRUB installs fine now on Sun partition tables without any further ado?
For my tested configuration - t5220, atomic recipe, single disk - yes.
4. And, just to be safe: Your previous mail contained hashes
before the partition layout lines (#). You did not actually
have those in your atomic file, correct?
Correct, those # marks were just for "markup" and not included in the
actual recipe I modified from the installer environment.
