I wrapped portmaster, since -af has the same problem when something screws the
build (mostly plist problems and $me wanting backup packages, but also
classics like using sudo as PM_SU_CMD and trying to reinstall it).
Basically, I made a list of all the installed ports and sorted dep order, then
called portmaster -u for every port and if successful put an empty file
+PM_DONE in /var/db/pkg/<pkgname>/. On a restart the ports containing a
+PM_DONE file are skipped.
If the entire process finishes successfully, all +PM_DONE files are removed. I
briefly looked into building it into portmaster, but that looked to take
longer then I had time for. The main loop is at the bottom, perhaps Doug likes
the idea and has the time to integrate it.

Or your websites in /usr/local/www, your database in /usr/local/pgsql or your
squid conf and cache in /usr/local/squid. Especially when pkg_delete -af does
the right thing and leaves all this in tact, I don't see the value of rm -rf
/usr/local, other then a few minutes on a process that's likely going to be
several hours or days.
