Re: [O] [OT] Requiring packages which may be missing?

[Tim Cross]

You do need to be careful when sharing your .emacs.d between machines to
ensure you use something like gitignore to exclude things you may not
want to share across systems (such as auto-save files, various command
history files etc). I've found the use of use-package and init.el in a
git repo the best combination.

With respect to packages changing, you can use the options in elpa to
pin a package to a specific version. The use-package macro also support
this.
