I've updated a machine in another country remotely from
NetBSD 4.0_STABLE to 5.0_RC1 like this:

1.) Put NetBSD 5.0 kernel (with COMPAT_40 enabled!) and
    NetBSD 5.0 sets on the machine.
2.) Install kernel to /netbsd and reboot.
3.) Untar userland (don't forget the "p" option of "tar"),
    run "postinstall" and fix all problems, install new
    bootblocks and reboot.
4.) Re-build all pkgsrc packages (in a change-root).
5.) Get rid of "COMPAT_SA" in the kernel configuration
    to get rid of that problematic code with the next
    kernel update. The functionality should already
    have been disabled by "postinstall".

        Kind regards
