Yes. The FAM facility is being used by another piece of software I work with, called bcfg2. Reports from the bcfg2 creator are that there are two primary packages to implement FAM, and he has found that "gamin" is the preferred package. I don't remember the reasons, but I remember being convinced. Other than that, It would definitely work. When any file gets changed in the entire image heirarchy, gamin would notify us. The trick would be in waiting an appropriate time after the activity happens, before trying to update the tarball, but it's certainly doable. The notification is pretty much instant. You touch a file anywhere in the heirarchy and the kernel tells you via gamin. The problem is, knowing when the events have ceased. Perhaps the thing to do would be to watch for the change of a single file, like /etc/systemimager/IMAGE_RETRIEVAL_TIME (or similar), and simply touch it whenever you're ready for a new tarball to be created. >Comments?? > >One issue I see right off the bat is that some times you want to install RPMs >into the image, but you can't do that in a chroot if the RPMs are not >available inside the image directory... If I understand correctly, that's one of the problems that si_imagemanip is supposed to address.
