Package: bootcd
Version: 2.53
Severity: normal
There are a number of bashisms in bootcd version 2.53 (currently found
in etch) that cause it and boot CD images created with bootcd to fail
when dash is used as /bin/sh.
dash is a strictly POSIX-compliant Bourne shell that is frequently used
to speed up shell scripting on older or minimalist systems. Personally,
I have found that using dash instead of bash can speed up boot-up times
by as much as 30%.
If you want to get a quick survey of where the problems might be,
install the devscripts package and try the following:

I think that the 'echo -n' complaints can be ignored as well as the
missing hash-bangs in the .libs, but the rest should be fixed. Either
that, or specifically use "#!/bin/bash" as the first line of your
scripts.
