So, today I managed to blow up my server. Interestingly, the jails are still working- at least until a reboot. I was updating the main server, and had a failed installworld... actually the command I got was because installworld, for updating the jails, was failing. So, for everybody out there, never run this unless you are 100% sure you need to:
make -f Makefile.inc1 install
It overwrote my libc before failing... and all recovery methods have failed to date. So, I have a few options now. 1. Hope I never have a power outage, and keep everything running.
