1.3.1 - 12/23/2001
------------------
Added both a Reboot and Halt button to the UML Box. Both of these buttons
have an interface to mconsole, and provide clean control of rebooting or
halting a Linux virtual machine. When they fail, Abort does all the clean-up,
but this should be used as a last resort. Sysrq interface will be added next.
Both of these buttons parse the Options entry for the first instance of umid,
and use this to identify the Linux virtual machine, so this value can be
changed to control a different running machine with these buttons.
Added a new stage button in the Yard Box called Copy. Create is now Copy, and
the uml_exclusively and genext2fs behavior are handled by Create, this is
much nicer because a new filsystem type can be created without having to wait

Although genext2fs only allows a normal user to create a UID/GID 0 root
