The patches are being applied to the compressed snapshot, not to the
ports tree.


The main three commands are 

fetch    - create or update the compressed snapshot from a remote server

extract  - extract the entire snapshot over the ports tree and
           initialize hidden metadata under the ports tree.

update   - compare metadata files and extract parts of the snapshot that
           have been updated 


It's not hugely wrong to adopt a tree installed from a tarball. The
issue is that obsolete files that are outside of a port directory and
weren't installed by portsnap wont be deleted automatically. Usually
such files will be ignored, but there is a very small risk that they
might have an effect.

The original point of the tree from the installer is that it was the one
used to created the packages on the installation media. This meant that
it was safe to mix and match ports and packages provided you didn't
update anything, other than applying security packages.
