While we wait for software updates, some of us, perhaps many of us
wish to run S6.0.x some of the time and S7.0 at other times.  In
the past, Blesser (1.1) was the method of choice for running multiple
systems from the same boot disk, or Apple's "startup disk" in the
control panel when the systems were located on separate hard disks.

With S7.0 old methods don't seem to work.  Blesser can't see S7.0's
system file to bless it so that doesn't work anymore.  I am running
hard partitions under SilverLining (5.27) and "Startup Disk" doesn't
work.  I don't know if startup disk works with SL partitions or if
its the particular combination of software versions that is causing
it to fail

Right now I have S6.0.7 on one partition and S7.0 on the other.  In
order to get one or the other system to boot I either: (1) alter the
name of the partition so that the desired partition is alphabetically
first, or (2.)  Use SilverLining's DA to set the partition containing
the undesired system so that it won't mount at boot time.

Neither of these methods is very elegant.  Is there a better way?

(related aside:  What became of the command-option-double-click method
 of switch launching?)

My thanks in advance to you that can help.
