As suggested in the meetup on hangouts, rather than having specific installation targets .deb and what not, why do we not generate a oneshot #!/bin/sh script that detects the operating system that is it is on and uses steps to install Xwiki manually but correctly.
It would be exceptionally extendable and easy to use, if we have users on a more obscure operating system, lets see gentoo for example?
It could prompt or report the emerge command necessary or offer to run them its self, or perhaps the installation script detects the environment and creates a Make for that platform with the given options?
For added flexibility we could even base the script on perl, bearing in mind it is both a B and R dep for almost all operating systems and is almost certainly installed.
