There is no question here. *If* the script in question uses dash
spuriously, ie, it doesn't use features specific to dash but is actually
a Bourne shell script, replacing /bin/dash with /bin/sh should be
fine. If not, stuff is going to break sooner or later, either because
/bin/sh isn't really dash (eg, someone might use bash for that) or
because of difference between the busybox and Debian (d)ash forks.

This depends on the code of the script/ scripts in question and blindly
advocating to replace the shell chosen by whoever wrote the script with
a generic name is not a good idea.
