sysupgrade(8) only describes what sysupgrade does, not the rest of
the mechanism.
The boot loader looks for /bsd.upgrade with 'x' filesystem permissions.
If present it removes the x flag and boots. (I think this should be
documented in boot(8) for the various arch but is missing).
The install kernel looks for /auto_upgrade.conf (written by sysupgrade)
to use as a response file for the autoinstall(8) mechanism.

The email sent to root ("$hostname upgrade log") may contain
useful information.
For an unusual setup you may need to look into how the
install/upgrade script works, see /usr/src/distrib/miniroot.
