Installation package manager

[Slapparoo]

The idea for an installation package manager is:

• installs can be distributed in a compressed ISO archive <package>.<version>.ISO.Z
  the install archive would contain all the files to install and a manifest with information like the
• Downlaod URL
• Version number
• Dependancies (System, other installation packages)
  System provided installer function
• backup any files which will be overridden by the installer and the current kernel and Compiler into an <package>.<version>.uninstall.ISO.Z or uninstall.<package>.<version>.ISO.Z
• Copy the files fom the installer package into the system
• Recompile kernal and compiler
• Maintain a System registry of packages which have been installed (and the order)
  System provided uninstall function
• uninstall all package installs which have come after this install
• uninstall by deleting all files which came in th einstall package from the system, then restoring all the files in the uninstall ISO (including the kernel and Compiler)
• reinstall all the install packages that cam after

Some system level utilities for quering whats installed, what files were provided by an install etc.
