You can, in your mind, remove "Debian" and "Gentoo", and if it 
pops up, also SUSE and Redhat and whatever, because it's a 
generic linux problem.


Seo Sanghyeon already proposed a way to solve this:

and I might even implement it, but I don't have much time for 
this, so feel free to grab it and implement it faster. :-)
