I personally do upgrades over SSH all the time (by skipping the single-user step) but there are reasons it's not recommended. If your new kernel doesn't work or play nicely for some reason you don't want to be stuck with a world newer than your (reinstalled) old kernel. If the system doesn't come back up multi-user for any of a variety of reasons then you won't have SSH access, etc. You should have good backups and a way to get console access if it's needed. That said, it usually works--especially for small incremental upgrades (7.0 to 7.1 or just different points along the same -STABLE branch, etc). So in a nutshell there are no guarantees but if you have an adequate bailout plan it can be a timesaver. JN
