They created another virtual fielsystem because the current /sys and /proc entries seemed to fail to do something consistently = as UEFI developed and was grafted on the current kernel.

You don't need to worry about efi > variables. Leave them alone and they will do you no harm. They are a problem and present a securilty risk. I can't change anything and nobody asks me about OS design, but it does cause = real problems and I run into them repeatedly at installfests. -- = So many immigrant groups have swept through our town that Brooklyn, like Atlantis, reaches mythological proportions in the mind of the world - RI Safir 1998 http://www.mrbrklyn.com = DRM is THEFT - We are the STAKEHOLDERS - RI Safir 2002 http://www.nylxs.com - Leadership Development in Free Software http://www2.mrbrklyn.com/resources - Unpublished Archive = http://www.coinhangout.com - coins! http://www.brooklyn-living.com = Being so tracked is for FARM ANIMALS and extermination camps, = but incompatible with living as a free human being. -RI Safir 2013 _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
