I apologize for the two-day lag in posting. I managed to seriously damage the kernel and file system (don't ask!) while trying to upgrade the kernel for yet another hardware encoder. Since the d*mn thing was cutting edge tech (for Linux), I was guessing at a couple things and guessed wrong.
So far, I've got my system rebuilt, minus a whole bunch of tools and data. I'm going to have to wait until the weekend to restore off of the backups. I've got enough in "draft" to cover posts until then.
