Now that Jessie is released, I ping you again regarding this issue. I'd
love to soften the disk unlocking prompt displayed by cryptsetup during
boot process. So did you (or the debian-desktop team) come up with an
alternative suggestion for the prompt yet?

At the moment, the prompt is as follows:

> cryptkey="Please unlock disk $diskname: "

where $diskname is:

> if [ ${cryptsource#/dev/disk/by-uuid/} != $cryptsource ]; then
>         # UUIDs are not very helpful
>         diskname="$crypttarget"

>         diskname="$cryptsource ($crypttarget)"
> fi

In other words, if $cryptsource starts with '/dev/disk/by-uuid/', then
$diskname contains only $crypttarget, otherwise it contains both
$cryptsource and $crypttarget.

$cryptsource is the source device name (e.g. /dev/sda1 or
/dev/debian-vg/root or
/dev/disk/by-uuid/b2629cd2-3565-48f6-910e-3ef091268491) and $crypttarget
is the target device name as specified in /etc/crypttab (usually
something like sda1_crypt).

Problem is, that both seem rather arbitrary to users who used the
automatic partitioning by debian-installer. My suggestion is to drop
$cryptsource completely and just display $crypttarget in the prompt.

Probably then we could improve the naming of $crypttarget in
partman(-crypto) code from debian-installer and use more descriptive
names like "system-disk"?

Any suggestions?

Cheers
 jonas
