This is just an idea.
New system for installing programs in Linux.
Unzip firefox.tar.bz to say /programs/firefox.
start as root "install.sh" script which creates links in /usr/local/bin or libs
links to firefox files:
ln -s /programs/firefox/somefile /usr/local/bin/somefile (or just ln to directory)
remove/rename /programs/firefox dir. Start "deinstall.sh" script,
which would remove orphan files. (Files that link to nowhere,)
usability of already created binary packages (slackware ones?)
usable accross most distributions. (when talking about binary distribution)
use of $KDEDIR, or programdir :) or $settingsdir on all distros
possibility of offline installation (no need for internet while installing)
easy install, deinstall.
no need for multiple packaging for every distro.
can be downloaded from internet, while in non linux sistem (unlike klik.)
(Note: I am aware of Gobolinux, PC-BSD, and klik. They all need recreating of current install packages.)
