For now, there are no immediate plans of replacing /bin/sh
with dash, but the possibility remains for the future.


I am a fan of this. Debian does this already, and it would dramatically speed up
shell scripts:

   $ cat alfa.sh
   x=400000
   until [ "$((x -= 1))" = 0 ]
   do :
   done

   $ time bash alfa.sh
   real    0m5.735s

   $ time dash alfa.sh
   real    0m1.112s

Dash can handle large scripts; I am already using it with one (545 SLOC):
