I agree. Petitboot is mentioned on IBM's website [1] so I suspect it is 
rather standard on IBM POWER machines.

AFAIK the only implementation of Petitboot on arm64 (Odroid) supports 
ext4 so there is no need to rollback to ext2. I did not mean to roll 
back to ext2 but to create a separate /boot partition only with LVM, as 
I do not see the benefit of a separate ext4 /boot partition without LVM.
