i stick with snapshots - rarely do make build's these days unless i'm
actually testing or doing something(tm).

you can also do this while in the ramdisk kernel:

once the shell is returned to you:
 /mnt/usr/sbin/chroot /mnt
 TERM=vt220 /usr/local/sbin/mergemaster -r -t /root/upgrade/etc
 exit
 reboot

the TERM needs to be set for gdiff3(1).

this way, the off chance that you need to reboot again is gone, due to
start-up changes and whatnot.

not quite - see below ...

no need to cd

tar zxvhpf etc38.tgz -C /root/upgrade/etc

(-p is the important one.)

no need. once you've booted into the new environment:

pkg_add -u

(if you are < sept 4th (-u will print you one command to update all the
packages - cut-n-paste....if you are running anything past sept 4th, -u
will do it for you.)

now for the daring, and *unsupported* way, you can do in place snapshot
updates as well....so as not to complete encourage it, see the
install/upgrade script to see how it is done directly within the ramdisk
(hint: 2-4 line script snippet). warning, this is not offically
supported, for something sometimes need to be in addition, such as
running MAKEDEV and such, which the ramdisk-based upgrade does for
you/etc/etc/etc.....but for the daring and willing...
