Possibility for FreeBSD 4.11 Extended Support

[Christian Walther]

Could be a reference to the Linux world, where every odd kernel
version number (e.g. 2.1, 2.3, 2.5...) are considered
experimental/development kernels. When a kernel is suggested to be
"stable", it gets a new version number. 2.5.X becomes 2.6.0
eventually, which marks the end of the V2.5 development.

I guess that's why he mentions kernel.org. I never downloaded a
FreeBSD kernel there. ;-)
