We do run bind on cerf, which gives us a secondary  DNS server in case
postel goes off the air.  You make changes on postel, sudo service
bind9 reload, and cerf picks up the changes automagically.

Because bind is straightforward, an industry standard, pretty much
bulletproof, and easy to admin.

But it's not as portable as just copying a zone file to another server.

That's not a good reason ;)  Also, anything djb related makes my skin
crawl.  OK, maybe yours is a reasonable reason too!

Just a tad ;)
