[pkg-cryptsetup-devel] Bug#491867: cryptsetup: README.initramfs.gz Section 9 is borked (decrypt_derived does not work with luks)

Package: cryptsetup
Version: 2:1.0.6-3
Severity: normal
File: /usr/share/doc/cryptsetup/README.initramfs.gz

Section 9 ``The "decrypt_derived" keyscript'' from README.initramfs.gz
is borked: It does not work the way it is described. Sticking with the
text step 4 will fail because:

* cryptstuff: the precheck for '/dev/the_device' failed:  - The device /dev/the_device contains a valid filesystem type crypto_LUKS.

I suggest fixing or removing that section. According to my understanding
decrypt_derived technically cannot work with luks, so a relatively
simple fix would be to fix the two crypttab lines to use the same config
as decrypt_derived and especially mention that it will not work with
luks.
