Q:

Excluding a git remote from "fetch --all"

Is it possible to have configured remotes in git that are only fetched when formally requested by its name? So they would be excluded of operations like fetch --all.
Imagine a dormant (disabled, or something) remote called "my-no-auto-fetch-remote":
$ git fetch my-no-auto-fetch-remote

(it's fetched)
$ git fetch --all

(the my-no-auto-fetch-remote shouldn't be fetched)

A:

There is a configuration skipFetchAll for remotes.
From the documentation on: https://git-scm.com/docs/git-config/1.9.2

remote..skipFetchAll
If true, this remote will be skipped by
  default when updating using git-fetch[1] or the update subcommand of
  git-remote[1].

As there is no option at command line when adding or changing a remote, I had to put that configuration editing the .git/config file, as:
[remote "my-remote"]
        url = git@the-repository-url
        fetch = +refs/heads/*:refs/remotes/my-remote/*
        skipFetchAll = true
