This is where it would be nice to be able to set (via SYSTEM CONFIG) an
arbitrary name with an arbitrary value and be able to query it from any
virtual machine. But without that we have to usurp other functions. I use

the GATEWAY value, setting it in the system config based on which CPU I i
pl
on. Perhaps even the PRODUCT enable/disable statements could be used to a
dd
our own pseudo-PRODUCTs and enable then in our home system config, but
disable in our DR system config. Then once things get straight at DR,
manually issue the PRODUCT enable commands and xautolog the appropriate g
uests.
