I want to use git to keep track of files inside /etc but do not want to do it as a super user. Is that possible to put GIT_DIR under my home directory and add public-read files inside /etc? Or that it could be done in some other ways.
Thanks.

You can use the core.worktree config variable in order to specify a worktree (/etc) which is not directly above .git. For your git commands to find the .git dir you would need to set GIT_DIR or use the --git-dir parameter.
I have found, though, that several git commands require you to be within the worktree or else they become confused. I use a shell function for that, doing something like "gg ~/path/project log" which requires ~/path/project.git to have its core.worktree set. Also, having a git alias like "git view" set up for gitk helps calling gitk in that way. git-gui makes unfounded assumptions and is completely unhappy in a situation like that.
I think the situation around GIT_DIR and and worktree is a bit in the flux at the moment (panta rhei..) but it works for me.
Cheers, Michael
Here's the "git go" bash function. I'm not proud of it, it makes several assumptions and does no error checking. Use it like "gg path/project command parameters" if the git-dir is "path/project.git" or "gg path/project/" if the git-dir is "path/project/.git". Have your core.worktree set in the former case, and also in the latter if the worktree is not "path/project".
I'm sure it can be done much better using helper functions from git's bash-completion, e.g.
gg ()
{
local _gg="$1";
shift;
local _ggwt=`git --git-dir="${_gg}.git" config --get core.worktree`;
if [ -z "${_ggwt}" ]; then
_ggwt=$(cd ${_gg} 2> /dev/null && pwd -P);
fi;
local _gggd=$(cd ${_gg}.git 2> /dev/null && pwd -P);
pushd ${_ggwt} > /dev/null;
git --git-dir=${_gggd} "$@";
popd > /dev/null

Michael, thanks for pointing out worktree being the trick to use.

I did the really easy hack (on my /etc BTW) and it worked fine for me.
I created a master project folder under ~home, init a new git repo, then symlink /etc/ onto an etc/ in the project dir, added all etc/ files. I like the extra a/etc/fstab in the patch files better then a/fstab.
And it is a life saver, payed it's effortless in gold. Some shining new distro should come up with a git based management system and it will leave all the other distros in the dust.
Cheers Boaz

I create a symlink in ~/gitrepo/etc to /etc and git init an empty repo there. However it failed in symlink when I tried to add files. Could you give more detail how to do it? Meanwhile I use worktree method as suggested by Michael.

What? I don't know this is what I did:

(I use git ver. 1.6.1, git-xxx is already deprecated) I followed your example, and failed in the git add,
gitrepo$ git add /etc/fstab fatal: '/etc/fstab' is outside repository

Sorry it's a typo, sure you must add files relative to the base directory (one containing the .git/ dir)

Hi Boaz,
I still could not add the file. This time it said symbolic link error.
gitrepo$ ll -A total 4 lrwxrwxrwx 1 bill bill 4 2009-01-22 17:54 etc -> /etc drwxr-xr-x 7 bill bill 4096 2009-01-22 18:23 .git gitrepo$ pwd /home/bill/gitrepo gitrepo$ git add etc/fstab fatal: 'etc/fstab' is beyond a symbolic link

OK so it looks like it is something new. Good to know I will not upgrade for now as I do use it a lot. Unless there is some config nub that can be turned. I must say that it is most useful, I use it everyday.
Someone please comment why are symlink not allowed. Is that because it might be dangerous? but so is a gun I might shoot myself in the leg, but they are still been sold.
