Any idea how this could have happened after disabling everything in
my /etc/loader.conf, and simply running a:

make buildworld
make buildkernel KERNCONF=myconfig
make installkernel KERNCONF=myconfig


well your supposed to do this single-user, run mergemaster and a few other
things.
I also don't see a make installworld.


I usually perform those steps after I've rebooted to ensure that my system will boot off the new kernel, as per the instructions in the FreeBSD handbook.

Joe, please try booting from a 6.2-release install ISO. If it works without
panicing,
then you did something wrong during the upgrade.


Downloading the image now, I'll let you know if I'm able to boot from it...

Since by your own admission your not an expert, you would be well advised to simply back up your files the old fashioned way, reformat your hard disk,
install from a 6.2 boot ISO, then restore your files.  Leave the fancy
in-place
updating to someone else. It's a big PIA and doesen't work half the time
anyway.



How well does simply upgrading with the CD work (as opposed to wiping clean)? I've upgraded several times to new releases simply by rebuilding world, it has never failed me in the past. I don't doubt what you are saying here, but since I will have to change how I work, assuming that I can boot off of the 6.2 CD, I'd appreciate any general upgrade tips that don't involve wiping the disk clean (which is not really an option).

For instance, is rebuilding world between point releases (e.g. 5.4 to 5.5) an okay idea, compared to across major releases (e.g. 5.5 to 6.2)?


I'll do my own homework regarding this too, but I appreciate any nuggets of wisdom you might have! As far as me being an expert, I guess I'd categorize me somewhere in between complete newb and FreeBSD developer =)



Thanks again!
