Re: port-atari/40316: "df: not found" printed while MAKEDEV all runs on NetBSD Atari install

Mmm, unfortunately I don't even have a working NetBSD system up and running 
to patch the sysinst disk with.  (sad but true)  Would it be possible for 
you to alter the existing sysinst image (from HEAD) with this change and 
then I can try that out.

Or if you're reasonably confident this will work, just submit the change and 
if it turns out to be problematic I'll file a different PR later.  =)

Thanks for the fix!
