1. it might be old stuff that really isn't needed anymore, as already
mentioned by others

2. portage up to a short while ago had a bug (or feature?!?) that when
you emerged a package for the first time and used -u to do this, it
would not be added to the world file. Nowadays it does the right thing
and adds it to the world file if you use -u or not. This means that
possibly some packages that you emerged yourself and weren't pulled in
as dependencies by other packages in the world file are now regarded by
--depclean as unnecessary, as they don't appear in the world file
themselves and aren't dependencies of anything in there.

This means that you'll have to go through the list resulting from a
'--depclean -p' and have to see if you truly wanted that package, and if
yes, re-emerge that package or add it to the world file yourself.

Once you're done remerging the stuff you want to keep and have cleaned
out the rest, it would probably be best to check that everything is ok
with a revdep-rebuild

In the future though, everything should work fine just as you were doing it.

Where do we easily find a list of "necessary" files, system files etc... so we
dont inaverdently remove them? For instance I am using udev for some time
now, can I let depclean remove devfsd?
