My Dotfiles

Base Flow

On a new system

Run:

sudo ./ubuntu_setup.sh

Among other things this makes sure the users from the wheel group have passwordless sudo.

Add those wheel users yourself, with sudo usermod -a -G wheel USERNAME for an existing USERNAME.

I've made the user toor to have a dedicated prompt with zsh, but the choice is ultimately yours.

To add a user

First:

sudo adduser --encrypt-home {name}
sudo ./govern_user.sh {name}

Log in as this user in Gnome. In there:

• Launch Chromium.
  • This creates its config dir.
• Close Chromium and start it again.
  • This offers to set it as the default browser.
  • Pin it to the dash is wanted.
• Close Chromium.

Then run:

./setup_user.sh

This should configure the Chromium profile, plus set the wallpaper and the profile pic, plus unpack user-specific files.

Done!

Quick way to grab this repo.

wget df.dima.ai -O df.zip && unzip df.zip && mv dotfiles-main dotfiles

dk — Docker Dev Container

dk launches an ephemeral Docker container with your user identity and a zsh shell.

Git repo passthrough

When you run dk from inside a clean git repo, the repo is automatically available inside the container:

1. dk clones your current branch into .dk.tmp/upstream and starts the container.
2. Inside the container you land in /app/<repo-name>/ — this is the clone.
3. Make commits as usual.
4. When you exit the container, dk detects new commits and prompts:

   Pull changes from dk container into <repo-name>? [Y/n]
   

   Pressing Enter (default: yes) fast-forward merges the changes into your host branch.

If the host repo has uncommitted changes, dk refuses to start and lists what's dirty.

Running dk from a non-git directory gives a plain container with no repo.

Claude Code in dk

Claude Code is pre-installed in the dk container. On first use you need to authenticate once and save the credentials:

1. Run dk — you'll see a message that Claude is not configured.
2. Inside the container, run claude and complete the authentication flow.
3. Run save_claude_dk_setup — this snapshots your ~/.claude directory.
4. Exit the container — dk picks up the snapshot and saves it to ~/.dk.claude_key on the host.

On subsequent runs, dk automatically restores ~/.claude inside the container.

The c alias runs claude --dangerously-skip-permissions for convenience.

To re-authenticate, delete ~/.dk.claude_key and repeat the steps above.
