Hi Bryan,
	I understand portmgr’s reasoning for removing these knobs as it improves “portability” (builds and runtime won’t depend on broken code), but I see the merits of making a separate package for Linux “compatibility” for the various items that people have brought up (mostly the LDAP issue and the vendor/legacy script portability issue). Plus it makes the barrier for entry lower, and less of a reason for Linux users to complain about how FreeBSD is different from Linux. Adding these as options to the port(s) won’t work for various reasons, two of which came to mind are:
	1. People should be able to install packages from FreeBSD.org instead of having to roll their own ports with custom options.
	2. It’s best not to build other packages on unportable (/bin/bash) behavior.
Thanks!

PS I don’t agree with Fedora/FreeDesktop’s push to move everything to /usr (I think it’s a wee bit radical, to say the least, and seems like it’s optimizing the wrong thing), but it’s something to keep in mind as this non-portable decision may start working its way into upstream ports: https://fedoraproject.org/wiki/Features/UsrMove .
