Michał,

Thank you for the hard work.

This GLEP implies that users need to have the entire repository to validate
and authenticate, if I understand it correctly.

For example 
PORTAGE_RSYNC_EXTRA_OPTS="--exclude=<list_of_<package/categories>"
wil still work but the resulting tree could not be authenticaed. as
the top level signature would fail. 

The manifests would still work correctly because they only apply to
the directory containing them. Pruning the repository at 
rsync time will therefore remove the manifents and the files that they cover.

Is that understanding correct?
