Hello Do we have a smart way to monitor a whole filesystem hierarchy for changes? kqueue seems a good answer at a glance, but as far as I understand, I need to setup a filter for every single file and directory in the hierachy, and this can quickly hit kern.maxfiles. Of course kern.maxfiles can be increased, but that hints this solution may not scale very well.
I also though about crawling on the hierarchy using FTS functions and look for ctime/mtime newer than previous crawl, but that can be CPU consuming. Any idea how this can be done efficiently? -- Emmanuel Dreyfus [email protected]
