I've only been using Linux for around 10 years as my only desk and laptop OS and this is the first I heard of XDG user dirs! This laptop runs Arch. Thanks for the heads up.

I'll drop "/etc/papersize" in return. If you are not familiar with this and do not print to letter paper then you will find it very, very useful.

Oh wow. If this does what I think it does, I'll be forever grateful for that comment.

It really does make CUPS, Libre Office and all the rest believe you when you say "I want to print on A4, yes A4, no not fucking Letter, A4, end of!" Obviously, substitute your paper size of choice. It probably even lends itself to some form of scripting and perhaps could be changed in reaction to events from say NetworkManager. Whatever.

My life at home is now worth living every time the wife hits print. Such a simple idea - brilliant.
