Bug#455508: [Pkg-cryptsetup-devel] Bug#455508: cryptsetup: should add blowfish, serpent and twofish to initrd

 I'm not quite sure I understand. If you setup a blowfish crypto device in
 /etc/crypttab, then the blowfish module will be copied to the initramfs.
 The unconditional copying of aes is just there as a safety net.

Ah, I didn't realize that I need to update initrd after I changed the
alghoritm. I didn't use cipher argument in /etc/crypttab and just
recreated LUKS volumen with another cipher. I was suprised that system
didn't boot because the standard initrd didn't contain basic modules.

I think that MODULES=most schema for initramfs *should* include the
four basic crypto modules and with MODULES=dep schema cryptsetup
scripts *should* guess with one is used.

Thank you.

Package: cryptsetup
Version: 2:1.0.5-1
Tags: patch

The installer allows to choose crypt algorhitm (aes, twofish,
blowfish, serpent) but cryptsetup copies to initrd only one of them:
aes.

I.e. for slow CPU systems the blowfish alghorims seems to be a better choise.
