Get this. I just generated a custom kernel to get rid of all the good stuff that this laptop will never support. It just so happens to be a couple of days later (in CVS terms) than the one I was running. I decided to take a chance and just do the installkernel rather than install the whole world. Now ntpd works. I didn't change any config files, DNS, or anything else - just installed my custom kernel. I still get an error message, but now it simply says "no IPv6 interfaces found" and runs successfully. Go figure. My best guess is that my prior cvsup of 5-STABLE had something in the kernel environment and ntpd slightly out of sync, with ntpd being ahead of the kernel, and now, even though I didn't do an installworld, that skew was resolved. While rare, it is the possibility of this skew that makes me uncomfortable with cvsup - but having no better plans, I'll keep using it! I may have to figure out how to maintain a "local release" tree that is behind the -STABLE tree, or something. I truly do not know what the right answer is. -- John Lind john@starfire.MN.ORG
