It's just one of several things that could go wrong. > I never had that problem as I updated by putting bsd.rd on the HDD > and booting it. Assuming that you are running -release rather than -current, and you are upgrading from one -release to the next one, then doing what you describe, I.E. copying the new bsd.rd to the existing system and re-booting in to it, means that you are booting the new bsd.rd using the bootloader from the previous version. Any new bootloader code that is part of the new release would not be involved in that initial boot. If you had downloaded one of the official image files, then that would be different, as the binary bootloader code included on that would be the version for that -release. Although doing what you describe can be expected to work almost all of the time, it caused problems a while ago for a number of users who were upgrading from something other than the immediately prior -release.
