Sure, but I was thinking retrieving the list of reserved port by a
database query, using network :)

Anyway, I just feel your argument is not applicable.

Our kernel is capable of doing an intersection for us, we dont need
to forbid user to mark a port as 'reserved' if this port is already
blacklisted by another mechanism (for example, if this port is already
in use)
