Howdy,

I've found the following sequence to be optimal from going from
pre-dirpref -current to post-dirpref -current and 4-stable to -current:

make buildworld
make buildkernel KERNCONF=YOUR_KERNEL_HERE
make installkernel KERNCONF=YOUR_KERNEL_HERE
make installworld
mergemaster
<reboot to single user>
fsck all partitions, answering yes to all prompts
tunefs -A -s <n> all partitions, where N > 0

I found that the newer fsck didn't help any.
