[Pkg-cryptsetup-devel] Bug#475838: cryptsetup: Would like to use decrypt_derived with a source mapping other than that of the root filesystem

[Sam Morris]

Package: cryptsetup
Version: 2:1.0.6-1
Severity: wishlist

I only have /home encrypted, not the root filesystem... my crypttab
looks like this:

durandal-home_crypt /dev/mapper/durandal-home none luks
durandal-swap_crypt /dev/mapper/durandal-swap durandal-home_crypt cipher=aes-cbc-essiv:sha256,size=256,hash=sha256,keyscript=/lib/cryptsetup/scripts/decrypt_derived

However the initramfs hooks only include the durandal-swap_crypt in the
initramfs, thus I get an error, "decrypt_derived: failed to find
durandal-home_crypt in dmtable" at boot time.

Alternatively, if there is another way to set up encrypted swap so that
I can hibernate to it, I would love to hear it. :)
