Differences between revisions 2 and 3

Upgrade, flask, sage 4.7, and ext4 filesystem

People: W. Stein, J. Grout

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.
