In response to popular demand, I am now providing both GENERIC and SMP kernels via FreeBSD Update to people running FreeBSD 5.3. To take advantage of this on your FreeBSD 5.3 (and only 5.3!) SMP system, run the following commands as root: # touch /boot/kernel/SMP # freebsd-update fetch (this should mention downloading a new /boot/kernel/SMP file) # freebsd-update install (likewise, this should mention installing /boot/kernel/SMP) # echo 'bootfile="SMP"' >> /boot/loader.conf and reboot. You should now find that `uname -ri` outputs "5.3-SECURITY SMP". Note again that this does not apply to any FreeBSD releases other than 5.3. Colin Percival
