Author: bdrewery Date: Tue Sep 29 18:51:56 2015 New Revision: 288390 URL: https://svnweb.freebsd.org/changeset/base/288390 Log: When stopping ugidfw, it is not enough to just try unloading the module. If the module is built-in to the kernel then the kldunload will fail. Rather than do this just check if there are rules and then remove them all. Add requirement on FILESYSTEMS to ensure /usr is present for /usr/sbin/ugidfw and /usr/bin/xargs. This was already effectively the ordering from rcorder(8).
