Bug#472233: openssh-server: bashism in /bin/sh maintainer script

[Raphael Geissert <atomo64@gmail.com>]

Package: openssh-server
Severity: normal
Version: 1:4.7p1-4
User: debian-release@lists.debian.org
Usertags: goal-dash

Hello maintainer,

While checking the list of packages reported by lintian at[0] I've confirmed 
with the latest checkbashisms (from the 'devscripts' package) that one or 
more maintainer scripts make use of a bashism.

checkbashisms' output:
> possible bashism in ./config line 65 (echo -e):
>   echo -en '\0\0' | 3<&0 sh -c \
> possible bashism in ./preinst line 278 (echo -e):
>     echo -en '\0\0' | 3<&0 sh -c \

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.
Please be aware that although bash is currently the default /bin/sh there's a 
release goal for Lenny to make dash the default /bin/sh[1].

If you want more information about dash as /bin/sh, you can read:

For more information please refer to the Debian Policy section 10.4 supporting 
this argument at:

HINT: sometimes these bugs are already fixed in Ubuntu, look at the PTS
