/bin/sh to /bin/bash is standard on Red Hat-derived systems.

dash is present as a package in RHEL6 and Fedora, but not EL7 or EL5.
Prior to that (<=EL4) 'ash' was available.
So, is changing the shell in /etc/passwd for the xymon user to /bin/dash
sufficient to get xymon to use dash or are other changes required.

I really do not want to change the symlink for /bin/sh to point to dash
as I am not sure what other things might break.

This is on a Centos 6.5 box.
