I don't think so... read on

You are right, that is the reason why there is a distinction between
scripts that have a .sh, and those that don't. If you really want
your script to be sourced in the same shell, then you give it a
.sh extension. Otherwise, it will be sourced in a subshell. So, when
portmgr has finished with the ports rc.d plumbing the apache script will
be installed without a .sh extension, and will thus be sourced in a
subshell.

Cheers.
