ello, my boot is broken. I installed the new kernel (3.0.36?) last night with
aptitude, but I run torsocks with it. It was late and I cancelled the thing
(WRONG!). Before shutting down the computer with 'shutdown now' (and then
pressing the power button), I did 'dpkg --configure -a' '/usr/bin/aptitude
install linux-image-' and had to come back from bed, because the laptop was
not off. I pushed the power button, and went to sleep. This morning, grub is
telling me that it can't find my root partition which is encrypted with
dm-crypt (cryptsetup). For what I have read, this might have to do with
initrd.img not loading the dm-crypt modules, but I don't know. I end up being
in a busybox shell that tells me that root is not found (that is
/dev/mapper/Lap-root).
I tried doing a chroot by first mounting the encrypted drive:

So... can someone help me? Should I give more info?
Thanks!
