James,

Go to http://reason.marist.edu/patches/bootshell-1.3.cc for the source.  The
instructions on how to compile it are very simple:
g++ bootshell.cc -o /sbin/bootshell

Then edit /etc/inittab and replace
 1:2345:respawn:/sbin/sulogin /dev/console
 with
 1:2345:respawn:/sbin/bootshell

Then, insert a CP SET SECUSER <ACCOUNT> command in the guest's PROFILE EXEC
to authorize an account that may use CP SEND to issue the halt command.
(#CP SEND linux390id HALT)  Make sure the SECUSER is your VM automation VSM.
Update your VM automation to send the halt command to all your Linux/390
guests as needed.

Re-IPL your Linux/390 system.  (To avoid the IPL, you could use the hcp
command by Neale Ferguson to issue the SET SECUSER command, and put that in
a startup script so it won't be lost the next time you re-IPL your system.)

The bootshell program will then "sit" on the VM console waiting for either a
halt command, or a "login" command to allow login to the console.  The halt
command can come from either the SECUSER, or the real console.

Peter Webb:

Could you detail exactly how you do this? I've never heart of that
bootshell.
