The RAs typically start with #!/bin/sh, so whatever that points to on
your system is what will be used.

You'd have to change the RA that includes them.

You can either edit the #!/bin/sh line at the top of each RA, or figure
out how to point /bin/sh to a Bourne-compatible shell. ksh isn't
Bourne-compatible, so I'd expect lots of #!/bin/sh scripts to fail with
it as the default shell.
