In that case, a note that lsof should be added to PORTS_MODULES on
/etc/src.conf. lsof uses several undocumented kernel interfaces that are
not stable (as they are not intended for external use). As a result, things
can break if the kernel is updated without lsof also being updated.

PORTS_MODULES will take case of this for those who build the kernel from
source. Things get rather messy if you use freebsd-update or packages
though, as the packaging system sees no reason to make a new lsof package.
I have no idea how to properly handle this. I simply always build lsof from
source and lock it so 'pkg upgrade' won't touch it.
