alt Hacker NewsThis is for when you have to ssh into some machine that's not yours, in order to do debugging or troubleshooting -- and you need your precious dotfiles while you're in there, but it would be not nice to scatter your config and leave it as a surprise for the next person.
This installs into temp dirs and cleans it all up when you disconnect.
Personally, my old-man solution to this problem is different: always roll with defaults even if you don't like them, and don't use aliases. Not for everyone, but I can ssh into any random box and not be flailing about.
Even with OP's neat solution, it's not really going to work when you have to go through a jump box, or have to connect with a serial connection or some enterprise audit loggable ssh wrapper, etc

Why would you want to ssh into a machine that's not yours? That's a violation of the Computer Frauds and Abuse Act, up to 10 years in prison!
There's definitely something be said for speaking the common tongue, and being able to use the defaults when it's necessary. I have some nice customisations, but make a point of not becoming depwndent on them because I'm so often not in my own environment.
On the other hand, your comment has me wondering if ssh-agent could be abused to drag your config along between jump hosts and enterprise nonsense, like ti does forwarding of keys.
