Description alexandreprovencio 2020-04-30 05:56:44 AEST

Hello Guys,
on my use case, i really don't need anything that is created on `~/.ssh`, except for the `known_hosts` file.

I like the way the XDG specification works, so I tried changing the value of UserKnownHostsFile to something like `~/.cache/known_hosts` which works fine, but ssh still creates an empty `~/.ssh`.

Can it be avoided or is it really hardcoded?

There is no way at present. Since ssh assumes pretty deeply that ~/.ssh exists, to implement this properly would require that ssh search its configuration for anything that may write to that directory before it stopped doing so.

Most of the uses I can think of are on the server side, and most of those (and the client for that matter) are read-only.  I'll try moving it and see what breaks.

create ~/.ssh on demand

~/.ssh/known_hosts is the only thing I could find.

ssh-keygen does its own thing which looks more or less ok.
