How to enable

Heavily based on this article and adapted from the Arch guide.

1. Install required packages: sudo dnf install pamu2fcfg pam-u2f
2. Generate the key mappings pamu2fcfg > ~/.config/u2f_keys

   If you have multiple hardware keys, you need to run the following for every subsequent key: pamu2fcfg -n >> ~/.config/u2f_keys

3. Move it so it can be used for centralized authentication: sudo mv ~/.config/u2f_keys /etc/u2f_mappings
4. To use it with GDM/GNOME, you need to edit this file: sudo -e '/etc/pam.d/gdm-password'

   And add the following line underneath the `pam_selinux_permit.so` entry: auth sufficient pam_u2f.so authfile=/etc/u2f_mappings cue

5. And for sudo, it’s a similar process; edit the following file: sudo -e '/etc/pam.d/sudo'

   And add a similar looking line for line 2: auth sufficient pam_u2f.so authfile=/etc/u2f_mappings cue

6. swaylock: sudo -e '/etc/pam.d/swaylock'

   and add the following line (before `auth include login`, if that’s present): auth sufficient pam_u2f.so authfile=/etc/u2f_mappings cue

   Press the key button and then enter to log-in

Poetry

All good, don’t forget to enable completions As of 2022-04-22: fpath+=$ZDOTDIR/zfunc (before compinit) poetry completions zsh > $ZDOTDIR/zfunc/_poetry

Nix

home-manager

Guix

On a new system

• Add all channels: guix pull -C ~~/.config/guix/channels.scm
• Install packages defined in manifest: guix package -m ~~/.config/guix/packages.scm

Maintenance

• On a foreign distro:
  • upgrade the build daemon by running: sudo -i guix pull
  • if the distro uses systemd also run: systemctl restart guix-daemon.service
  • don’t forget to upgrade the guix channels sha every now and then
  • Fedora: Use `dnf history userinstalled` to see which packages have been installed and to replace with guix packages
  • Ubuntu: Use `apt list –installed` to see list of installed packages

Do not forget

• /usr/share/applications/[...].desktop cannot be executed: Remote peer disconnected Open the desktop file, look for a DBusActivatable=true line and comment it out An alternative solution (running exec dbus-daemon --session --address=unix:path=$XDG_RUNTIME_DIR/bus) didn’t seem to work for me…
• Unable to connect to /run/user/1000/sway-ipc.1000.3043.sock export SWAYSOCK=/run/user/$(id -u)/sway-ipc.$(id -u).$(pgrep -x sway).sock
• Build fails with 8GB space on /tmp - No space left on device mount -o remount,size=15G /tmp Adjust size to your needs

Known issues

• [sway] Coming back from sleep doesn’t restore the laptop screen (it’s all black)
• [sway] Reloading sway/returning from sleep causes firefox-wayland to crash
  • workaround: don’t use `input *` to switch kb layout
• [waybar] Disappears every now and then
  • “workaround”: run `nohup waybar &` to restart it
  • last incident on 2022-03-15
• [sway] reloading sway sometimes does not load gammastep
• [firefox] Doesn’t use $XDG_CONFIG_HOME
• [thunderbird] Doesn’t use $XDG_CONFIG_HOME
• [tmux] “SSH/Mosh aware username and hostname status line information” from oh-my-tmux
• [kodi] Doesn’t use $XDG_CONFIG_HOME
  • Setting $KODI_HOME doesn’t seem to be working, kodi still looks for ~/.kodi and creates it if missing
• [zsh] has to be installed on the fedora side as well, otherwise the OS doesn’t see the PATH to the guix version and reverts to bash.
• [swaylock] & guix: swaylock needs to be setuid to read /etc/shadow
