Yes- /bin/sh is a symlink to /bin/bash, in the bash package. dash
cannot install this symlink as it would obviously conflict (although
if Ubuntu can do it...). Pacman simply shells out to /bin/sh, so if
you create the relevant symlink, things will just work with dash as
well.

See near the end of the PKGBUILD:

P.S. There is a new version of dash in [testing] if anyone has
noticed; I was going to wait for signoffs after the ISO release.
