greearbany 'casper' developers here, or folks familiar with adding stuff to the initrd?15:43
greearbI think *fsck needs to be added to the initrd and run on the casper-rw file before mounting it, otherwise a system crash can corrupt casper-rw and you can never boot properly again unless you manually fsck casper-rw on a different machine...15:48
dileksgreearb: think most of the ubuntu developers are at UDS16:04
greearbnod...trying to hack it myself..should no soon how hard that is going to be.16:05
