The patches I posted for namcap documents what would be left (the one
related to /lib at least). It will throw warnings for the things we
can move without patching (libraries and systemd unit files (assuming
Dave will flip a needed config switch)), but will not complain about
stuff that would require (one line!) patches (like the location of
udev rules).

The patching I mentioned would only be a transitional measure which
would be reverted once the symlink is in place, it is really an
implementation detail.
