I now have a dedicated ESP on /dev/sda2 (non-RAID) and it boots via gummiboot (-> UEFI). dracut assembles the arrays after configuring this: # /etc/dracut.conf add_dracutmodules+="lvm bash mdraid" hostonly="yes" mdadmconf="yes" # the uuids of my two arrays ... kernel_cmdline+=" rd.md.uuid=7663e24a:1a64ce0f:49545629:46742031 " kernel_cmdline+=" rd.md.uuid=8c266e7a:870c97b7:ff199683:6d8c3edb " # end (lvm isn't necessary but doesn't hurt) I now wonder if I could (a) create a RAID1 over /dev/sd[abcd]2 and format it as vfat ESP or (b) "clone" /dev/sda2 -> format each /dev/sd[abcd]2 as vfat, copy the content of /boot in there and install gummiboot to each harddisk ?
