Upgrade, flask, sage 4.7, and ext4 filesystem

Database
If we stick with the filesystem: NEED a very fast filesystem that supports > 4 million inodes and > 32000 directories per directory, i.e., ext4. This is difficult because boxen and sage.math are both Ubuntu 8.10.
- Also, want to at a minimum have user and worksheet metadata stored in database so startup is faster.
- Could run the server in a virtual machine, which would support ext4. But are virtual machines fast enough these days? They weren't last year. This would be worth trying.
Current Servers
Backup Strategy
- ?
Untrusted User Code: must all be executed in a virtual machine
- ?
Monitoring
- Nagios -- investigate for monitoring
Or extend this script: http://wstein.org/home/wstein/bin/watch.sage
Virtual Machines
- I tried install virtualbox 4 on sage.math and failed, due to the Linux source and Linux kernel being out of sync somehow. Probably just needs an upgrade and reboot.
- I am scared to upgrade virtualbox on boxen.math.
- The Virtualbox on boxen.math is somewhat unstable and very old.
