Ah, I thought there was a workaround to get the combination of mdadm+luks working. Currently with your above suggestion it fails to boot post install at grub with: error: file `/gnu/store...-raw-initrd' not found. > You’re welcome to start working on it if you feel like it (and I’d be > happy to help!) and/or submit it to bug-g...@gnu.org. I wish. Maybe one day. My coding skills are MIA and time is very limited. But I do hope to start contributing in some way in time (besides my FSF financial support). > I hope this is a bit clearer now! Thanks. :-)
