Picking a random (i.e. most recent) post to reply to.

I don't really care what the default PATH is, I always set it to my
liking anyway. I understand all the historical arguments but I don't
think they matter too much these days anymore as times and OSes do change.

I feel that the / vs /usr split is rather pointless on modern systems,
but I do like the bin vs sbin split because it makes my life easier
(which is the entire point of any env var when you think about it). When
working as a user I'd rather not have my tab completion results
cluttered with apps I have to be root to use properly.

I vote to leave things as they are, and I also vote for showing people
who don;t like it how to change $PATH
