Hmm, I can't seem to get that to work with Solaris /bin/sh.  I've tried
"echo ((ls))", "echo $((ls))" and "echo $(ls)".  Only "echo `ls`" works.

I would just stick with `` when you don't need nesting, for the same
reason you would use `expr blah` rather than $((blah)).  Actually, I'm
not sure there are any systems that don't have /bin/bash installed, and
this is the Linux automounter after all, so perhaps $() isn't a bad
idea.
