However, I have one machine that is pretty much dedicated to one specific function, and for it, I thought I'd try freebsd-update. And over the last year or so, it's worked pretty well: I have the machine set up (as is usually my approach) to be able to boot from either of a couple of slices. I use a "dump | restore" pipeline to copy the / and /usr file systems from the "active" slice to the "inactive" slice, adjust /etc/fstab on the inactive slice to reflect reality for when it's the boot slice, then (while the file systemms =66rom the other slice are still mounted -- e.g., on /S2) run "freebsd-update -b /S2 fetch install", then reboot from the newly-updated slice. In the past, that's Just Worked. This weekend, though, I was planning to update my other systems tfrom stable/10 to stable/11, so I figured I'd try freebsd-update on this machine first. But before I tried going to stable/11, I thought it might be good to first get to the latest releng/10. Running freebsd-update seemed to go well. I rebooted from the updated slice... and found that I could not ssh to the machine. (I only physically login to a machine other than my laptop if there's a problem that's so bad that I can't login from the laptop....) And I found that sshd wasn't running. Indeed, on attempting to start it by hand: root@sisboombah: # service sshd start Performing sanity check on sshd configuration. Undefined symbol "ssh_compat13" referenced from COPY relocation in /usr/sbi= n/sshd /etc/rc.d/sshd: WARNING: failed precmd routine for sshd Attempting to start it in "debug" mode was of no help: root@sisboombah:/tmp # `which sshd` -d Undefined symbol "ssh_compat13" referenced from COPY relocation in /usr/sbi= n/sshd Any clues? I have placed both a typescript of the freebsd-update run (actually, a pair of them: one yesterday; another, today), as well as a typescript =66rom some poking around a bit, under . Thanks!
