I have a feature request: I'd like to be able to perform all the maintenance tasks at the command line. I've been looking for ways to offload loads from my laptop, which is a small and silent one, to my headless server, which has plenty of power. Recently, I managed to exhaust the RAM of my laptop when rebuilding fingerprints. My server hosts the MySQL database and the files, so it should be better done there. There's an open bug #254099 on running new image scan on the command line. That bug also links to some others, but this wish extends those and scopes it clearly to the actual tasks in the Maintenance dialog under Tools. If these were available on the command line, all these maintenance tasks should be able to run on the server. It would also enable people to run background maintenance as cron jobs, as well as quickly trigger maintenance that you may want to do without needing the GUI up.
