Chronos repo sync hooks

.chronos_sync.md

apparently the first alphabetical name is the name of the gist, otherwise this whould be readme.md

prereqs: gem install socksify

do a ./pull.sh at least once into this repo and when you clone it use the flag --recursive

because gists dont allow subdirs, hooks_setup.sh should be hooks/setup.sh go ahead and fix all of those and chmod +x both the pre-* hooks.

and run hooks/setup.sh to set the hooks up

I know I am breaking git by forcing one continous commit stream like this is CVS or something. But these are running configs on the server, maybe later I will branch them but for now, git is a versioned scp, sorry.

.gitmodules

[submodule "chronos"]

hooks_README.md

hooks included:

pre-commit which forces you to use an up to date repo (I know this is not how git does, but it is needed for this use case). If you need to bypass this run git commit with the --no-verify option.

pre-push which pushes changes to chronos assuming you have a connection to hera. Add [skip] if you dont want to deploy. (Note, I only check the last commit being pushed.)

Personalization:

Ty https://mpdaugherty.wordpress.com/2010/04/06/how-to-include-git-hooks-in-a-repository-and-still-personalize-your-machine/

if any developer does decide to add their own hooks in /hooks/personal/, they should be sure to add a line containing /hooks/personal/*[^.sample] to the end of their /.git/info/exclude file so that git will ignore their customizations.
