I'm looking for a job control system for Linux. Before you ask - quite aware of cron and at :-)
What I want is something where I can set time windows for jobs to run in, priorities, and some simple dependencies, maybe some retry rules.
In the Big Enterprise World this is AUTOSYS or Control-M. There's also the Open Source Job Scheduler, but it's Java-based and I suspect a memory hog. Most of these jobs will be running on relatively small-memory VPS systems (256MB-2GB memory)
I search SuperUser.com but didn't see much in the way of answers...
