comment Upgrading old FreeBSD system
The point about COMPAT_FREEBSD6 is a very good reminder. Thanks for that one. I don't have a mirror or ZFS. However, I do dump the entire filesystem to a tape every weekday. Between that a a boot CD, I should be able to recover from a disaster. Thanks again!

@Sunny: Thanks for the URLs. My big issue is that I usually have tried so many things (many of which are complex and/or lengthy) that I couldn't list them all.

comment Upgrading old FreeBSD system
I should have said this first: Thank you. The through reply was really appreciated. I do have backups. Redundant backups, in fact. (Tapes and a disk-to-disk-to-offsite Barracuda system.) I've started setting up a VMware environment to test the upgrade, too.

comment Upgrading old FreeBSD system
I agree about regular updates. My upgrade woes aren't a sysadmin issue. They're from management / institutional culture. I need at least 6 approvals (no exaggeration) before making a shutdown and those people tend to not reply to my requests. Then they tend to kill the few outage requests that are approved. Usually at the last minute. Lately, I've been building redundancies (e.g. 2nd web proxy & an Open Directory replica) to make it easier to do upgrades. When I first started using FreeBSD, outage time was easy to get. User/management expectations changed around 3-5 years ago. :(

Nevermind. I looked it up. Sorry. I should have done that first. I'd be happy to accept an answer I received if it worked. So far, not a single answer to a question I posted has been a working solution. One sent me in a new direction, but ended up being verifiably false. The rest were ideas that I either already tried and ruled out or not even on-topic. I don't want to accept an answer and end up misleading someone who finds my "endorsement" of that answer.

comment [Strange]Mac OS X unable to use Proxy and Custom DNS setting
I'm confused. Tell us more about the network's topology. Is it a cable modem in a house, a corporate LAN, etc.? Also, using the program "Terminal" int he "Utilities" folder, have her type "netstat -rn". Then try to ping the default route and the DNS server.

comment Centralised Authentication - Recommendations?
And if you invest in Active Directory as your "root" authentication, you can add a Mac Open Directory server for managing those Macs. Look for articles about "the golden triangle" for that.

comment a fallback web server
I'm not sure that this will work. Any given client will cache the FQDN resolution and then go to just that one server for the next 24 hours (or however long the DNS cache period is.) That doesn't deliver a very quick switch to the still-live server. In fact, when the cache expires there is no guarantee that the next DNS query will go to the still-live server. I could be wrong, but I always thought that round-robin DNS was always about load balancing and not fail-over or redundancy.

comment FreeBSD hardware recommendations
Thanks for the suggestion of the chat room. I'll check that out when I get a chance. BTW, enterprise hardware is typically sold for 6-18 months. So any answers here can still be useful to others until about November 2012. So in addition to helping me with this issue, the answer would be helpful to others for quite a while.
