Well, those extensions (${VAR#%} ) aren't - they are standard POSIX.
But my experience is that almost noone knows about that.

I don't really like it that ksh has stop() as a builtin - looks like
namespace pollution to me. However there's nothing we can do about it
I guess..
The /etc/init.d/skeleton script uses d_start and d_stop already, so
using those would be the correct fix then I guess.
