Here's one way to do it. Get the ubuntu package source:
sudo apt-get source mythtv
sudo apt-get git-core
Import the ubuntu source into a git repository (note you can also pull
into a git repo directly from svn repo if you wanted to).
Create an empty repo:
Add the source files and commit them:
git add *
git commit -a -m "Imported source."
Create a local branch to make your changes:
git checkout mybranch origin/master
Make your changes to file foo.cpp
git add foo.cpp
git commit -m "My local changes."
Build the ubuntu debs (sorry can't remember the exact command for this)
and install them.
When the upstream source code changes:
Now when git fetches upstream changes to the source your local commits
will be rewound and replayed on top of origin/master, which is the
definitive upstream version of the code.
Carry on working on your local branch and rebuild the debs.
If the git pull merge fails with a conflict:
1. Edit the code to fix the problem
2. git add the file to mark the conflict resolved.
3. git rebase --continue
4. repeat 2 and 4 if required until the merge completes.
This allows you to play with your own changes and keep up to date with
the upstream source. When you are happy with your changes, you can
create a patch and submit it back.
