Arne Wiebalck 6e0d08c892 Software RAID: RAID the ESPs ... For software RAID in UEFI mode, we create ESPs on all holder disks and copy the bootloader there. Since there is no mechanism to keep the ESPs in sync, e.g. on kernel upgrades or when kernel parameters are updated, the ESPs will get out of sync eventually. This may lead to a situation where a node boots with outdated parameters or does not have any of the installed kernels in the boot menu anymore. This change proposes to RAID the ESPs. While the UEFI firmware will find an ESP partition (one leg of the mirror), the node will see an md device and all subsequent updates will go to all member disks. Also, remove the source ESP after copying in order to avoid mount confusion (same UUID!).
