Bug#690720: live-boot: bashism in /bin/sh script

[Raphael Geissert <atomo64@gmail.com>]

Package: live-boot
Version: 3.0~b6-1
Severity: important

Hello maintainer,

While performing an archive wide checkbashisms (from the 'devscripts' 
package) check I've found your package containing a /bin/sh script making 
use of a bashism.

checkbashisms' output:
>possible bashism in ./lib/live/boot/9990-misc-helpers.sh line 664 (read 
with option other than -r):
>                                        read -s passphrase
>possible bashism in ./lib/live/boot/9990-mount-iscsi.sh line 36 (echo -e):
>                        echo -ne $i\\r

Not using bash (or a Debian Policy conformant shell interpreter which 
doesn't provide such an extra feature) as /bin/sh is likely to lead to 
errors or unexpected behaviours.
