[pkg-cryptsetup-devel] Bug#789125: initramfs-tools: update-initramfs fails w/ random luks key for swap

[Brainslug]

Some more info:

The problem seems to be the "_" in the swap's crypto device name. If I
replace "sda4_crypt" with something that does not contain an underscore,
this works, for example:

sda4crypt /dev/sda4 /dev/urandom cipher=aes-xts-plain64,size=256,swap
sda5_crypt UUID=2fa9feb8-b096-41f7-bf17-41399ccc8004 none luks,discard

root at laptop:/etc# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-3.16.0-4-amd64
root at laptop:/etc#

However, underscore is not a problem on any of my non-swap devices, like
the root partition sda5_crypt. Only for the swap partition.


Thanks!
