I was able to boot the old kernel, but that didn't seem to help. Using /rescue/sh got me a usable prompt, and I was able to do a 'mount -a -t ufs' which got my hopes up, but trying to run 'make installworld' still gives me this: 


ELF interpreter /libexec/ld-elf.so.1 not found 
Abort trap 


I looked in /libexec and found ld-elf.so.1 and ld-elf.so.1.old 


I tried copying ld-elf.so.1 to ld-elf-so.1.new and .old to ld-elf.so.1 and rebooting the old kernel in hopes that it would work. No joy. 


Next I made a copy of the 8.2-RC# install disk and tried to do an upgrade in place. It was unable to backup /etc to /var/tmp/etc due to: 



ELF interpreter /libexec/ld-elf.so.1 not found 
Abort trap 


.. again. This happens pretty much anytime I try to execute a command that does not come from /rescue 


I really rather not do a clean install and lose all my configuration data, but it's increasingly looking like that may be my only option.
