Well, after some headscratching and physical inspection, it looks like this machine is booting and running from the same physical disk. It appears I never understood that you could boot from a different device than the one that was mounted and holding all your data *without realizing it* or being able to find out (ideally sysctl would reveal the device that the running kernel was pulled from: if it does, I can't make it out). It seems there should be some way to specify a boot device without futzing around in the BIOS or learn what device has been defined. dmesg doesn't even reveal that, as far as I can tell. It looks like boot.config might do some or all of what I expect. I also don't see how I can remove or rewrite just the MBR/bootsector on disk other than the active disk. If I could do that I could be reasonably sure I was booting and running from the disk I think I am. It may be time to stop pretending I know how any of this stuff actually works.
