Brandon9000,

Linux does not do patches the way windows does. It uses packages. Some versions even use deltas, but the crux of it is, you cannot do what you are trying to. It is a one way proposition. The only way to avoid that is to try to claim all updates they make to any configuration files owned by a package and store them in some sort of repository linked to the version they are associated with.

You will then have to uninstall the package, install the new package (old version or new version) and then apply the config file for that version, because configuration files sometimes change formats.

LINUX IS NOT WINDOWS BUT FREE. It is an entirely different OS with different structures. EVERYTHING in LINUX is a file. Windows is very different. Is Windows POSIX compliant? Can Windows change kernels on a running OS with a splice? Does Windows have initial ram disks?

What you want are ways to save machine states, but that is an all or nothing proposition.

Might it be possible to do what you want? Sure, but it will take a very clever person a lot of time, and even more code to do it, and even in those cases, they will probably find a corner case that will bite them on the ass so hard, they will bleed money.
