OK. Here is the sequence of what I did if it helps someone else.
Sony SAT T-60 with Instant Cake LBA48 on 250MB disk drive.
My goal was to avoid having the DST upgrade blow away the kernel and possibly lead to data corruption. So I took the following pre-emptive measures.
Copied Active system and boot partitions (HDA7 & HDA6) to inactive partitions so that they were mirror images with dd.
Fixed fstab in copied partition.
Unfortunately, when I "made the phone call" which on my system is done over the internet, and then the system rebooted - it hung on the "Installing software message..." and I had to unplug it which is probably what caused what I saw next.
So I pull the drives and the active partition HDA7 is EMPTY! but (Thank God) the inactive partition HDA4 has the mirror image that I copied to it.
So now I dd if=/dev/hda4 of=/dev/hda7 bs=1024, fix the fstab, and then put the drive back into the tivo.
Turn it on, welcome screen, Installing software screen, and it then boots up OK. I'll have to check whether other things look right (like if my kernel did get preserved properly).
Just tried TWP and Telnet and they don't work so I guess I have to pull the drive back out and run the nic configuration stuff. But otherwise it is running and receiving.
