+
+Just to add a bit to what Thomas has already said, I'm currently running
+cauldron via UEFI+GPT partions without an initrd (using
+"root=PARTUUID=xxxxx rootfstype=ext4" on kernel cmdline).
+
+/boot is my EFI partition which is FAT32 and thus doesn't support
+symlinks which some of our tools assume is allowed and thus need
+updating (e.g. for symlinking the config and the default initrds and
+kernel to nice names)
+
+I would generally promote this approach although care needs to be taken
+to lock down the permissions/mount options on the /boot partition such
+that regular users cannot read/write data on it - only root. This is
+easy enough to do, but something in drakx helpfully adds a permissive
+umask option to it - we'll need to fix that and perhaps add a special
+case for a fat32 /boot if it's detected.
+
+Oh and I'm using gummiboot as the actual bootloader.
