Hi,

'?' should show list of possible boot devices but this doesn't seem to
work with a src update from around 20031105-2024 UTC:

--- cut ---
...

Manual root filesystem specification:
  <fstype>:<device>  Mount <device> using filesystem <fstype>
                       eg. ufs:da0s1a
  ?                  List valid disk boot devices
  <empty line>       Abort manual input

mountroot> ?
panic: Root mount failed, startup aborted.

syncing disks, buffers remaining...
done
Uptime: 1m23s
Automatic reboot in 15 seconds - press a key on the console to abort
--> Press a key on the console to reboot,
--> or switch off the system now.
Rebooting...
--- cut ---

I tired multiple ties to ensure I only have a '?' as very first
character and only entered <?> <enter> via serial console.

Any ideas ?
