Hello,
Is it possible to hibernate to lvm? I saw the examples in google but it
seems to not work. I.e. it seems to hibernate correctly but it does not
resume. What's wrong:
% cat /usr/src/initrd.contents

file /bin/resume /usr/lib/suspend/resume 0755 0 0
file /bin/lvm /sbin/lvm.static 0755 0 0
dir /dev 0755 0 0
