etckeeper pushing to github

To preserve the current ssh keys for when you're in root, use sudo -E. That way there's no need to add anything to the root ssh config

One thing you can do is specify a key to use for one repo and set it as a remote in your git repository.

Meaning you can put this in root's ~/.ssh/config:

Host gitupstream
        HostName example.org
        User git
        IdentityFile /home/<user>/.ssh/id_rsa.pub

Assuming you git remote add gitupstream [email protected]:/myrepo in this case then do git push origin gitupstream.

If anyone has an issue with git still trying to use id_rsa instead of the key specified in /root/.ssh/config, here's my fix for it.

The following are my test configuration files before fixing them:

/root/.ssh/config:

Host bitbucket
    HostName bitbucket.org
    User git
    IdentityFile /root/.ssh/bitbucket.pub

[repo]/.git/config:

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
[remote "origin"]
    url = [email protected]:trae32566/test.git
    fetch = +refs/heads/*:refs/remotes/origin/*

There are two problems with this:

1. SSH seems to require you to use the "Host" variable in place of [user]@[address|domain]
2. The configuration file seems to need the private key.

To fix the first problem I edited line 7 in [repo]/.git/config from:

url = [email protected]:trae32566/test.git

to:

url = bitbucket:trae32566/test.git

To fix the second problem I edited line 4 in /root/.ssh/config from:

IdentityFile /root/.ssh/bitbucket.pub

to:

IdentityFile /root/.ssh/bitbucket
