Porteus

great stuff Hamza!

worked without problems for me

what about turning it into something bigger?
maybe you could create simple gtkdialog menu which would let the users choose which proprietary modules they want to create?

sample menu (multiple choice allowed):

a) nVidia current
b) nVidia-legacy (173.x branch)
c) nVidia-legacy (96.x branch)
d) ati-fglrx current
e) ati-fglrx-legacy
f) VirtualBox
g) vbox-guest
i) build everything

additionally VirtualBox script could ask about adding vbox extenstion pack (Support for USB 2.0 devices, VirtualBox RDP and PXE boot for Intel cards):
https://www.virtualbox.org/wiki/Downloads
and integrate it directly with Vbox xzm (have seen requests for that already).

i know it's a huge task but in case of success i would like to integrate your script in PSC or as a separate entry in system menu for Porteus-2.0.
this way users could stay up to date with latest drivers/Vbox and i wouldn't have to create them myself.
(7 modules multiplied by 2 archs always takes a lot of time).

let me know what you think about it.
