:-).  You can add an alias for it if you really want it.

I just remembered that it's `re' in my debugger too (except my `re'
stops at the reset vector and only works in real mode, and I have
variations for different reset methods).

sparc64 and powerpc have a variation named `reboot' that needs to be
untangled someday.  It is one of 50-100 undocumented commands.
Untangling it a little ... it is just bogus since it is an MD command
that is identical to the MI `reset' command except for its spelling.
All variations just call the MI interface cpu_reset().

sparc64 and powerpc also have a variation named `halt'.  This should
be an MI ddb command too.
