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
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
then you did something wrong during the upgrade.

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

Since by your own admission your not an expert, you would be well
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
updating to someone else.  It's a big PIA and doesen't work half
the time

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).

If wiping the disk really isn't an option then you have one or more of the

1) Production system with a lack of hardware spares

2) inadequate backup plan and execution.

People who state that wiping the disk isn't an option are screaming
at the top of their lungs for the hardware gremlins to explain what MTBF is
all about.

The gremlins will visit you, I guarentee. And they always pick the very
times for it too. I just hope (if this is your workplace) that your job

My production system is backed up daily to two different sites, that's not an issue. The system I'm thinking of upgrading to 6.2 is my test server I run out of my house that stores movie files and other non-essential files. Technically, wiping it clean *would* be an option if it came down to it, just an inconvenience. Perhaps I should invest in another HD to use for instances such as this.

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 =)

The problem is that all of the ports and packages that you put on a server change from release to release. The developers of openssl, for example,
don't give a tinkers damn about how FreeBSD's upgrade process works,
when they are making changes in their code.

I run a number of FreeBSD servers and what I do is simply keep them patched
with security updates.  Every once in a while a security hole will be
discovered in a non-core program and if it's serious enough I'll go into the
and do a "make deinstall" followed by downloading and compiling the program the "old fashioned way" I shoot for a min of 3 years on the OS before even
thinking about updating, and when it's time to update the hardware has
generally reached the old rag stage anyway.

Do you run any non-production machines where you test running newer OSes and test software updates and such?
