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.
