* There is no support for partition images, only whole-disk images are
supported with Software RAID. See :doc:`/install/configure-glance-images`.
+* In UEFI mode, the Ironic Python Agent creates EFI system partitions (ESPs)
+ for the bootloader and the boot configuration (grub.cfg or grubenv) on all
+ holder devices. The content of these partitions is populated upon deployment
+ from the deployed user image. Depending on how the partitions are mounted,
+ the content of the partitions may get out of sync, e.g. when new kernels
+ are installed or the bootloader is updated, so measures to keep these
+ partitions in sync need to be taken.
