I used this today manually installing a LEMP stack on a clean server - when I mess up the permissions and only find out later - I did not just bash the up key like usual!
(I came back to read this post, which probably took more time, but I may have learned something!)
I'm glad it was useful!
Yeah, that's usually how it is, the first few times you do it, it's going to be a bit slower, but once you've got it down it saves tons of time.
