Enough information is logged so that, at any point in time, it is possible to tell what images are being used. After collecting some stats for a while I hope to use this data to evaluate various strategies for preloading disks with images other than the default. Although not its primary purpose, enough information is collection to be able to get a snapshot of node usage at any point in time. This includes what nodes are being used and by who, as in which experiments and thus which projects. NOTE: For a while you might see a few of these warnings, *** WARNING: os_setup: *** could not find previous state (rsrcidx=484084) in image_history *** table, won't be able to determine newly allocated nodes if someone does a swapmod to an experiment that was swapped in before this commit was installed. This is because os_setup uses previous information in the table to determine newly allocated nodes. This warning can safely be ignored in this case, and should go away over time.
