[ofb] Downtime tonight.

Hi, We're going to be working on OFB again tonight. This will result in a few reboots and probably some time where ofb is in a single user mode and so unavailable, but will require no further action from others. The list of tasks we're looking to complete tonight includes: - Resizing OFB's RAM. We rebooted last night due to running out of memory. - Adding a swap disk. - Converting /home from ext2 to ext4. - It being ext2 is why the reboot this morning took over an hour. Plus things will be faster after the conversion. It's going to take us a while to get set, so there will be a bit before any reboots, so if you have questions or comments, fire away. I'm probably going to keep most updates to #miniofb on slack <https://ofb.slack.com/archives/C2A4BR7KL>;, and maybe a wall or two on ofb. There will also be an all clear email when we're done. Chris
