Gary,

Wow. If you are missing glibc, I am not sure I can help you. You need to
find a static mount command and cp (possibly on rescue images). If you
can do that, just suck the glibc stuff onto a flash drive with those and
move them over. From there, you should be able to start rebuilding.

Otherwise, you are correct, likely just better to copy data and
configuration information off the system and reload.

Good luck,
Trever
