This morning, I tried to migrate to unencrypted /, encrypted /tmp /var
/home and swap, but messed it up and made my system unbootable. I've
just installed xubuntu from a daily build of the karmic alternate
livecd (be warned, you need a deb of ttf-bitstream-vera lying around,
because it's not in the repositories any more, but is still depended
I made a 256mb /boot and put everything else on a crypto fs. I put a
LVM volume on that, made a volume group containing a swap LV and a
root LV. Hibernate works (I just tried while typing this post).
I'm not sure if the guided encrypted LVM option would work.
