Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:

/*
 * Open profile dir - find in about:support or about:profiles
 * Copy this file into your profile directory.
 * Add changes to this file. Save file.
 * Restart Firefox. Below overrides will be loaded.
 * Close Firefox and open prefs.js to confirm changes merged there.
 * NOTE: only non-default values will be saved to prefs.js
 *

Aborting 'yum upgrade' can cause CentOS7/RHEL7 to have "duplicate packages" installed.

To fix, you could manually run below commands for every affected package (using correct format of package-version or just package name):

rpm -e --justdb --nodeps <package-old_version>
yum reinstall <package>

Or use below commands to avoid manual work.
