atom# uname -a
FreeBSD atom.localdomain 7.2-RELEASE-p1 FreeBSD 7.2-RELEASE-p1 #0: Tue
Jun  9 18:02:21 UTC 2009
root at amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  amd64

atom# du -hs /boot/kernel*
205M    /boot/kernel


This is on a stock 7.2-release/amd64 updated to -p1 with
freebsd-update, 2 kernels is the maximum that would fit into the
default 512mb partition size for /, a bit too tight for my liking.
