GottZ Dotfiles

Configuration files, helper scripts and system settings for an Arch Linux workstation. The repo lives in /opt/dotfiles and is managed as root — most files are meant to be symlinked into /etc, /usr/local/bin, /usr/share or $HOME.

---

Quick start

sudo git clone https://github.com/gottz/dotfiles.git /opt/dotfiles

# symlink what you need, e.g.
ln -s /opt/dotfiles/etc/gitconfig              /etc/gitconfig
ln -s /opt/dotfiles/etc/DIR_COLORS             /etc/DIR_COLORS
ln -s /opt/dotfiles/etc/zsh/zshrc.local        /etc/zsh/zshrc.local
ln -sf /opt/dotfiles/etc/profile.d/*           /etc/profile.d/
ln -sf /opt/dotfiles/usr/local/bin/*           /usr/local/bin/
ln -sf /opt/dotfiles/home/.config/tmux         ~/.config/tmux
ln -sf /opt/dotfiles/home/.config/ghostty      ~/.config/ghostty
ln -sf /opt/dotfiles/home/.config/wezterm      ~/.config/wezterm
ln -sf /opt/dotfiles/home/.ssh/allowed_signers ~/.ssh/allowed_signers

Repository layout

etc/ — system configuration

Path	Purpose
gitconfig	Global git identity, SSH-based commit/tag signing, defaultBranch = root, rebase-on-pull, fetch.prune, zdiff3 conflict style, autoStash, histogram diff algorithm.
DIR_COLORS	Rich dircolors database for ls --color (based on default + custom extensions).
zsh/zshrc.local	Zsh config on top of grml-zsh-config — see Zsh section below.
ssh/sshd_config.d/99-gottz.conf	Hardened sshd: 10 s login grace, 1 auth attempt, key-only (no passwords).
sudoers.d/00_timeout	Sets passwd_timeout=0 — sudo never caches credentials.
docker/__hetzner.daemon.json	Docker daemon template for Hetzner nodes: IPv6, ip6tables, large address pools (172.32–192.0.0/12).
pacman.d/hooks/remove_old_cache.hook	Pacman hook: runs paccache -rvk1 after every transaction to keep only the last cached version.
modprobe.d/sound-powersave.conf	Disables power-save for snd_hda_intel and snd_usb_audio.
modprobe.d/usb-power.conf	Disables USB autosuspend, sets mousepoll=0 for lowest latency.
systemd/system/kanata.service	Systemd unit that starts kanata with the pocket3.kbd layout.
systemd/system/kanata@.service	Template unit — systemctl enable kanata@caps loads caps.kbd, etc.
kanata/caps.kbd	CapsLock → tap Esc / hold Fn-layer. Fn-layer provides media keys, mouse emulation (QWER/ASDF), browser back/forward. Targets Wooting, Fujitsu, AT, Cherry keyboards.
kanata/cleware.kbd	Cleware USB foot switch → mic mute (both keys).
kanata/pocket3.kbd	GPD Pocket 3 remap: CapsLock → tap Esc / hold RCtrl, Esc → tap CapsLock / hold RAlt, RShift → < (102nd key).

etc/profile.d/ — shell init scripts

Script	What it does
00-local-bin.sh	Adds ~/.local/bin, ~/go/bin, /opt/dotfiles/.bin to $PATH; sources ~/.cargo/env if present.
01-dircolors.sh	Evaluates dircolors -b via the custom /usr/local/bin/dircolors wrapper.
01-editor.sh	export EDITOR=nvim
dps.sh	Defines dps / dpsa — formatted docker ps with alternating bold rows and multi-line port wrapping.
ipinfo.sh	ipinfo <ip> — queries ipinfo.io Lite API (token from ~/.secrets/ipinfo).

---

home/ — user configuration

Terminals

Both Ghostty and WezTerm share the Kanagawa colour scheme (background #181616, foreground #c5c9c5).

Path	Details
.config/ghostty/config	Font: Pragmasevka Nerd Font. Kanagawa palette. Unbinds Alt+1–9 (conflict with tmux over SSH).
.config/wezterm/wezterm.lua	Font: Pragmasevka Nerd Font. Kanagawa colours. Kitty keyboard protocol. Auto-generates SSH domains from ~/.ssh/config (plain + multiplexed). Windows: detects OpenSSH agent pipe, builds launch menu (pwsh, PowerShell, cmd, Git Bash, Elvish, Nu, VS dev prompts). Linux: reads cursor theme/size from gsettings.

tmux

Feature	Detail
Plugins	TPM (auto-installed), tmux-sensible, tmux-fzf (Ctrl-f).
Keybindings	vi copy-mode (v/y), r reload config, g next pane, n/p next/prev window, {/} swap panes.
Status bar	Left: session name + attach count. Right: time + date, prefix/green indicator. Window tabs with Nerd Font icons for active, last, marked, zoomed, bell states.
Settings	50k history, base-index 1, mouse on, 256color + RGB, extended-keys.

Zsh

etc/zsh/zshrc.local — extends grml-zsh-config (pacman -S grml-zsh-config).

Feature	Detail
History	1M entries, dedup, ignore-space.
Modern replacements	ls → lsd (all aliases rewritten), cat → bat --paging=never.
File manager	y wrapper for yazi (cd-on-exit).
Fuzzy search	fzf --zsh integration (Ctrl-R etc.).
Node	Auto-loads nvm from /usr/share/nvm/init-nvm.sh.
tmux shortcut	tmx → tmux new -As <hostname> (auto-attach named session).
Docker aliases	dc, dcu, dcd, dcr, dcdu, dcl, dcdul, dcp, dcpu, dcpul, dce, dcb, dcbn, dcbu, dcbnu — full docker compose workflow. dcpua pulls all non-local images and recreates running compose services.
GitHub Copilot	gc, ge (explain), gs (suggest) via gh copilot.
Termux	OpenKeychain SSH agent setup when running in Termux.
Misc	root → sudo su -.

SSH

File	Purpose
.ssh/allowed_signers	Maps git@gottz.de / github@gottz.de to trusted ed25519 + RSA signing keys (used by gitconfig's gpg.ssh.allowedSignersFile).
.ssh/authorized_keys	Public keys authorised for SSH login.

usr/ — helper executables & system overrides

usr/local/bin/

Tool	What it does
needsrestart	Checks for deleted libs still held open by processes and compares running vs. installed kernel version. Exits non-zero if reboot needed.
dpsql	Connects to a Dockerized PostgreSQL: extracts POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_DB and container IP via docker inspect, then runs psql. Usage: dpsql <container> [psql flags].
loadavg	Compiled C binary — prints 1/5/15 min load averages.
colorcheck	Awk script — prints a 77-column truecolor gradient to test terminal capabilities.
dircolors	Wrapper around /usr/bin/dircolors that prefers ~/.dircolors, falls back to /etc/DIR_COLORS.
lscolors	Displays every LS_COLORS entry in its assigned colour with type descriptions. Useful for auditing the dircolors database.

usr/share/wireplumber/wireplumber.conf.d/

File	Purpose
no-suspend.conf	Disables ALSA suspend for the Hidizs ST2 PRO USB DAC (avoids the ~2 s power-on ramp on resume).
