I can verify that this works currently. I am using Ubuntu 10.10 in the following setup: Truecrypted windows partition. Truecrypted data partition. cleartext boot partition with intiramfs. dmcrypt partition w/ LVM containing swap & root. Suspend and hibernate both work dandy, and the only unencrypted place the system could put the hibernate file (/boot) doesn't have enough free space for that, by several times over. Not that it would try to put it there anyway. Maybe I missed something, but why was there a suspicion that this might not work? -Iggy > Arno Wagner wrote: >> On Thu, Jan 06, 2011 at 08:08:55PM -0800, Bryan Kadzban wrote: [...] >> Anyways, experimenting on this would nto be that difficult.
