i read that article too, and it is not that.
it is about creating a standard set of linux rules (like posix maybe a bit but more wide ranging and more contemporary) and then, any distros that voluntarily comply to these specs get given a certificate saying they are compliant.
This sounds like a great idea to me, newbies will know that UL certified docs will apply 100% to their distro so long as it is also UL certified.
There's nothing to stop, for example, slackware or debian from not bothering to comply, since a lot of people will still use them, those people will just know that their distro is not 100% compliant, which for people who already use those systems, might even be a good thing.
