That's quite awesome. Like most big perl shops, we have a lot of
perversity about our environment that makes the atime thing hard, but
this concept works perfectly! Just to give you an idea, we have
* noatime on all disks
* a separate install tree of Perl modules for each of a dozen
long-lived processes
* said daemons are crash-only (kill -9 == no END)
* some normal short-lived scripts, too
In addition to using END (for short-lived scripts) I'll just have the
daemons report daily, sweep everything up, et voila! A little cleaning
of the data, and I'd be happy to make it public.
