Example:

---- $FAI/disk_config/mpsd-srv-ibm-001 ----
# set boot flag on /boot/efi
disk_config /dev/disk/by-id/wwn-0x600605b002b15b50203efd9326bb4cf7 disklabel:gpt fstabkey:uuid bootable:2

# boot-related
#   first GPT partition: bios_grub, flag set in $FAI/scripts/BOOT_GRUB/10-setup
primary -          16M -    -
primary /boot/efi 128M vfat rw          createopts="-F32"
primary /boot     512M xfs  rw,noatime
# system partitions
primary swap       16G swap sw
primary /         100G xfs  rw,noatime
primary /var       0-  xfs  rw,noatime
