Actually I don't run desktop managers, just plain fluxbox over X.  And
I use X mostly to browse the web.  But any ways, I've run source based
linux distributions in the past, and although it's fun, my box takes
too much time to keep up with the rolling changes.  So I've learned
it's better to keep updating through binaries in this good old
boxes...

Ups, I didn't know that...  so freebsd-update only works on
-RELEASE's.  I'm not sure that was explicit in the documentation, good
to know, :)

So the only way to live in -STABLE up to date is to keep the base
system up to date through compilation...
