Regarding:

| will be changed to /bin/bash

-> can you try that please? I'd like to have a "grml works with /bin/dash as /
bin/sh" system once and we should start testing and working on that.

Argl, bring me a coffee. 8-) Thanks for taking care gebi, of course I'm talking 
about grml-crypt and not grml-vpn. :) Reopening therfore, adjusted title and 
removed release-stopper from topic.

Interesting :) Ok, I'll ask Thomas about the source of his current grml-vpn 
script, closing the bug as it's definitely not a bug anymore. :)

i don't know where you get that grml-vpn uses /bin/sh

% head =grml-vpn
#!/usr/bin/zsh

now i recall it, grml-vpn uses zshs ince ages, because with bash you can NOT
increment a variable inside a pipe reading while loop.

will be changed to /bin/bash

grml-vpn uses /bin/sh in the shebang line but uses non-POSIX syntax like
'function ...() {...}' in code itself - causing breakage on systems which use
something like /bin/dash as /bin/sh:

% grml-crypt mount ~/misc/Cryptofile cryptofs                              
/usr/sbin/grml-crypt: 53: function: not found                                  
         
Usage: "grml-crypt" [OPTIONS] action <device/file> [mountpoint]                
        
/usr/sbin/grml-crypt: 100: function: not found                                 
        
[...]

Thanks for reporting goes to Thomas Quaritsch.
