I am not sure why the /boot parititon is needed here. If you have sufficently large MBR gap to embed stage2 image, then it could boot off from LVM volumes directly.
We did that based in the Michael Chang's comment that is documented at https://github.com/yast/yast-storage-ng/blob/master/doc/boot-partition.md#ge...
Our conclusion from that comment was "ditching /boot is harder than expected, so to stay safe always propose /boot with LVM". That's reflected in the summary section here https://github.com/yast/yast-storage-ng/blob/master/doc/boot-partition.md#ge...
Ok, I understand the problems with grub-once, but: always creating a /boot with LVM makes snapshots/rollback with LVM impossible :(
Looks like this needs a further discussion with the bootloader people, if there isn't a solution for at least GPT based partition schemes or so.
"with raid, eLVM and LVM - on GPT always create a GRUB partition - otherwise, always create a /boot partition"
Isn't it?
Ok, and this is what we have today, fine with me.
Is the GRUB partition required in all architectures when LVM is used? Right now, for PPC64+LVM we always require /boot (similar to what we had in x86), as you can see in https://github.com/yast/yast-storage-ng/blob/master/doc/boot-requirements.md Should this current block [1] be something like this[2]? [1] with a LVM-based proposal if there are no PReP partitions requires /boot and PReP partitions if the existent PReP partition is not in the target disk requires /boot and PReP partitions if there is already a PReP partition in the disk only requires a /boot partition [2] with a LVM-based proposal with a MS-DOS partition table if there are no PReP partitions requires /boot and PReP partitions if the existent PReP partition is not in the target disk requires /boot and PReP partitions if there is already a PReP partition in the disk only requires a /boot partition with a GPT partition table if there are no PReP partitions requires GRUB and PReP partitions if the existent PReP partition is not in the target disk requires GRUB and PReP partitions if there is already a PReP partition in the disk only requires a GRUB partition Cheers -- Ancor González Sosa YaST Team at SUSE Linux GmbH -- To unsubscribe, e-mail: opensuse-storage+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-storage+owner@opensuse.org
