If you change the name or location of the shell to something other than "/bin/sh", plenty of legitimate software would break too.

Even though the POSIX standard says:

> Applications should note that the standard PATH to the shell cannot be assumed to be either /bin/sh or /usr/bin/sh, and should be determined by interrogation of the PATH returned by `getconf PATH`, ensuring that the returned pathname is an absolute pathname and not a shell built-in.

> For example, to determine the location of the standard sh utility:

command −v sh
