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=x 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.

We don't even have to wait for v2. Their current policy for certifying hardware for windows 8 is that Arm based devices _cannot_ be allowed to disable Secure Boot. So in the future they might expand that requirement to other hardware types. http://www.softwarefreedom.org/blog/2012/jan/12/microsoft-confirms-UEFI-fears-locks-down-ARM/ http://www.pcworld.com/article/248342/windows_8_secure_boot_the_controversy_continues.html > We are promoting freedom and open source, not MS crap. > > So the time to speak up is _now_ and fight this vendor lock-in.

For GPT, that works perfectly since a long time, and with more than 2TB there is not choice on old hardware, but that do work without trouble Chris.
