Does OS X not have packages like Debian or Fedora? Since VMware is mostly made up of binary files, does this mean you store entire binaries when differences arise (not that big a deal since disk is cheap)?
I believe it does have packages but how do you revert your Linux system after doing a yum upgrade? I don't think you can.
How would this work for a system that is under package management and you have to revert the database that goes along with the packages?
Seems to me that you would have to revert the whole entire system at once so that the binaries from the installed packages and the db go together.
I'm not sure I would see the need for this if a system has LVM and you can just take snapshots and then revert if something doesn't work right.
I have often said this about LVM also but I'm not sure how well it would work in practice. My main concern is that the snapshot is its own special volume. Your options then are to try to copy everything back out of the volume into your main system or to somehow try to remount or switchroot over to the snapshot volume and turn it into a regular volume which I am not sure is possible.
