Hi Sridhar: in one of the discussion threads you have asked about an .MSI like installer module for Linux.
Good news. Looks like there is one. It's called 'autopackage' Key Aspects . software distributed using autopackage can be installed on multiple Linux distributions . software installed, integrates well into the desktop environment. . it adds value, where RPM, Yast, Yum do not work so well non-core packages, programs available from internet, commercial vendors Please take a look at http://www.autopackage.org/ -- thanks Saifi.
