If I may add some advice I received here..
When you do follow -current and you want to update to the
"latest -current" download the latest iso and then use
"sysmerge"
Sysmerge is an awesome utility but it does
not give you a
fresh install with your configs..
so YMMV..
In the past I have tried to follow -current and since my boxes
are at remote location I followed the
-stable instructions
which do work in most cases unless your
"snapshot" is too far out of date..
Bottom line, for me, I have moved back to -stable as I want
my computer to
"work for me" not
work on my computer..
following -current is fun.. if you like that kind of stuff..
good luck...
