ok to the naming and multi zram devices questions:
1) one single large space is wasteful if you have your machine up for longer than a single (or series ) of heavy lifting operations --say you are rendering a video and then back to the usual grind stuff would you want all that extra space just wasted ? also say a follow up process is in need of more would you wanna be stuck on previous values? zram is dynamic in nature smaller more numerous /dev/zram$i allows for that and in a dynamic manner... 2) it the RAM its based off not swap and the "z" is known as dynamic Corey W Sheldon Freelance IT Consultant, Multi-Discipline Tutor 310.909.7672 www.facebook.com/1stclassmobileshine On Thu, Nov 27, 2014 at 7:39 PM, Reindl Harald <h.rei...@thelounge.net> wrote: > > > Am 28.11.2014 um 01:34 schrieb Zbigniew Jędrzejewski-Szmek: > >> On Fri, Nov 28, 2014 at 01:21:26AM +0100, Zbigniew Jędrzejewski-Szmek >> wrote: >> >>> On Thu, Nov 27, 2014 at 04:42:36PM +0100, Juan Orti wrote: >>> >>>> El 2014-11-27 14:48, Reindl Harald escribió: >>>> >>>>> Am 27.11.2014 um 14:25 schrieb Juan Orti: >>>>> >>>>>> Reindl, I'm of the opinion you should upload your scripts to some git >>>>>> repository and package them to be part of the distribution.
