Hi,

 Ali, firstly thank you for all the work you put in for the minimal specs
of what lubuntu will install on. To everyone else working on this, also a
big thank you.

For our minimal specs, once we get to 256MB RAM, we are also stretching the
applications (browser).

@ Jluien, if Z-Ram works so well, could we drop alternate for some of the
archs?

Regards,

Phill.
