My pleasure.

You did better than I did recently: I spent four days at it.

I'm with you there, Stefan. I find the whole RAID and LVM area deeply 
mysterious, and the docs I've seen only say what to do, not why. I'd still 
like to find a proper explanation of how it all works.

I've never had an initramfs, seeing no need in my case to keep /usr on its own 
partition.

As far as I know, the only thing that /requires/ an initramfs is having a 
separate /usr. And I can't help you with GPT or UEFI - sorry.

I sometimes say that life is just one long journey of discovery  :-)
