Based on some of the responses I've received, I don't think I
adequately described the problem before.
Imagine, if you will, that I choose to install the OS on bus 3,
target 0. This is what it looks like to 4.0f:

In this case, the drive I want to install on is rz24, so I count
disks and determine that it is going to be dsk12 on 5.1a, so I hope! I set
up my install.cdf file to install on dsk12, but when the install runs, what
happens if 5.1a renumbers the buses? (And it has happened)
For instance, what was bus 2 now becomes bus 3 under 5.1a, and vice
versa. It then installs onto dsk12, which would be what used to be drive
rz16, and perhaps writes over my data. I don't know of any way to predict
what 5.1a is going to do as far as numbering the buses.
Thanks for any input
