OP asks a relatively simple question, and gets scolded as it committed murder.
For all we know OP is the only user and is just playing with Linux, and just wants a simple (probably unnecessary) shortcut because he's GUI oriented.
This is kind of someone asking how to open their lunchbox easier, and get treated like they are giving a copy of their house keys to everyone in town.
Chill... Not everyone is running a maximum security level server. If OP screws their system (like most of us do at some point), I'm sure a fresh re-install would be enough for them.
Sure dude, EU and US, same principle, same as united nations, united airlines and IUPAC. Same principle, they are a union of things, if you mean that as "principle", sure.
EU doesn't have rules that everyone has to follow, they have agreements, that are often very specific between nations. UK was part of the EU with their own currency for example. So no, it's not the same type of union, unless you simplfiy it to "union of things"which of course is the same principle.
Also any member of the EU can leave unilaterally (like the UK), not so much for the US. I don't think they follow the same principle, again, unless you think of it just as a "union of things"
