How so?
: I have a patch set which allows a port to install KLD source in a directory
: and have it picked up during a build/install kernel. This has a few
: advantages over calling the ports tree from those makefiles. The prime one
: being that your source code does not change between upgrades without you
: saying so. This is matters since (for example) the newer nvidia driver does
: not work on some hardware the old driver does (eg Fx5200 Go). It also means
: that the kernel build/install does not result in non kernel things being
: altered.
How do your patches work? Do they work with multiple kernel trees?
: The disadvantage is that the KLD ports need to be modified to install the
: source code in the right place (not hard) and that you will need to upgrade
: your ports tree to keep up with ABI changes if you update your source but
: IMHO it's better to make this sort of action explicit - otherwise the end

I guess I'm a little unclear why this is better or worse than
PORTS_MODULES. I guess I'm missing the explicit step, since I only
ever update the parts of my ports tree that I'm upgrading with
portupgrade.
: Also speaking of KLD ports.. I really wish they wouldn't install
: into /boot/modules (I patch so they don't) as it is a really good way to
: shoot yourself in the foot during an upgrade :(
Usually this is only a problem when tracking or jumping to current,
but I understand...
