Correct.

Yes, but...

Don't use 'portmaster -af'.  It is faster to get a list of installed 
ports, delete them all, then reinstall.  There is a procedure at the end 
of the portmaster man page to do that, but it still refers to the old 
pkg_ commands.  I have a PR which updates that procedure for pkg:

Or you can use ports-mgmt/poudriere to build your own packages.
