Ah, now I know what you ment. However, I cannot really see the 
advantage in

  grub_probe=${sbindir}/`echo grub-probe | sed ${transform}`

with ${transform}="s,x,x,".

I rather reads like WTF to me... ;)


BTW, in another mail from 4 Feb you asked my if the
"echo ... | cut ..." mess in my script could be simplified with the
"echo ... | read ..." feature. I am sorry, but the answer is "no".

This is because read will run in a separate process and cannot set the 
variables in the parent shell, see 
<http://www.unixguide.net/unix/bash/E4.shtml>.

Cheers,
Fabian
