Re: Another Installer bug. xfs also not work...

Hello,

I would say we simply increase the size of the partition to 512 MiB. It feels a little bit wasteful, but there is not much else we can do if we want to continue supporting XFS.

I do not think there is any benefit in mixing partition types, because with XFS selected and VFAT being used for EFI and ext4 being used for /boot you would have a whole zoo of file systems not offering any advantage.

I have no idea what the state is out there that we can finally drop the /boot partition and systems with hard drives of several terabyte size would still be able to boot. So for that reason, I would like to keep things as they are and just enlarge the partition.

Best,
-Michael
