- Subject: Remove support for FreeBSD 4.x (and earlier)
FreeBSD 5.0 was released in January of 2003, and FreeBSD 4.11, the last
on that branch in January of 2005, so it appears time to remove support
for anything older than FreeBSD 5.x, if for no other reason to simplify
things a bit.
This simplifies the spec file a fair bit, and I would not be surprised
for even FreeBSD 5.x not to really work any longer.
On the way, move a now no longer relevant comment where it is still
applicable.
What do you think? (Let me know if you'd like me to keep the first
sentence of the original comment.)
