DFishburn It sounds like it's been a long time since you fiddled with it :) Unless you're making your own custom mach_kernel images, you're probably doing a dual boot w/kexec setup. In this case, no matter what the recovery image is booting briefly and then subsequently launching your ubuntu install. The new image helps this process with newer distros in 2 ways (at least).
1. it's supports ext4 which is the default on most newer distros 2. it should automatically read the grub.cfg file to boot properly I can't comment on the performance since I haven't compared any distros at all really :( There are various ways to perform the install, I won't go in-depth here http://code.google.com/p/atv-bootloader/wiki/BootingLiveCD http://code.google.com/p/atv-bootloader/wiki/InstallingLinux Those links should probably refresh your memory though. -- To post to this group, send email to atv-bootloader@googlegroups.com For more options, visit this group at http://groups.google.com/group/atv-bootloader?hl=en
