Closing the bugreport, Thomas please feel free to re-open it if you encounter 
any problems - thanks!

yes, grml-shlib will never be posix-compatible ;).

as i got no bugs from testers about grml-crypt with /bin/bash i'll release it 
during the day.

Great, I'll upload the package as soon as you tagged it. :)

Yeah, known issue - see http://bts.grml.org/grml/issue180

I once wrote a patch against grml-shlib which makes it POSIX compatible, though
Gebi (author and maintainer of grml-shlib and grml-crypt) does not want to use
POSIX-only. ;) There's a fix for grml-crypt (simply using /bin/bash instead of
/bin/sh) pending in our version control - just not packaged and uploaded yet.

Gebi, care to release 0.16 (currently tagged with UNRELEASED) so we fix this
issue? :)

thx! && regards,

I just installed grml-crypt and grml-shlib packages on Ubuntu Hardy Heron 
(8.04). 

ii  grml-crypt          0.15           wrapper around cryptsetup-luks
ii  grml-shlib          1.02.13        Generic shell library used in grml 
scripts

Apparently, Ubuntu uses dash as default shell for /bin/sh as it states to be 
POSIX compliant. 
But when I call grml-crypt (for example) with dash, the following happens: 

bene@hp:~/Desktop$ sudo /usr/sbin/grml-crypt
/etc/grml/sh-lib: 37: function: not found
[... similar lines omitted here ...]
/etc/grml/sh-lib: 68: function: not found
[: 78: Illegal number: -a
/etc/grml/sh-lib: 81: function: not found
/etc/grml/sh-lib: 86: vprint: not found
[... similar lines omitted here ...]
/etc/grml/sh-lib: 104: vprint: not found
/etc/grml/sh-lib: 106: function: not found
PANIC:
/etc/grml/sh-lib: 122: _syslog: not found
Terminated
bene@hp:~/Desktop$

Using bash, the behaviour is as intended:

bene@hp:~/Desktop$ sudo /bin/bash /usr/sbin/grml-crypt
Usage: "grml-crypt" [OPTIONS] action <device/file> [mountpoint]

grml-crypt is a wrapper around cryptsetup with LUKS support to format a device
