Might > this be due to boot with systemd? hmm, i wouldn't think so -- this is pretty low-level and should not be affected. make sure you have the hook in your mkinitcpio.conf, and make sure your not trying to rollback after a kernel update ... but you'll need to elaborate more on what "I can't use rollback" really means (eg. some output or description or something). that said, i haven't actually ran the hook for awhile -- i had to ease off the edge a bit -- and hence am running ext4 currently. but in light of recent grub2 developments, it sounds like kernel-level rollbacks will finally be possible so lately i've been trying to revisit this project. i'd also like to get the hook -- or some form of it -- included in Arch proper ... -- C Anthony
