* Installation
Installer does not recognize the touchpad, for some reason.

I wonder if Gnus will automatically pick this up?

Disappeared after ≈30s 🤷

Wooh touchpad works!  Although the sensitivity is a bit low.

Wifi LED is on, whatever that means.

Brightness function keys do not work on the login screen.

Using default config to get four workspaces.

Brightness and sound function keys work! 🙌

Touchpad click and scroll do not work.

Wifi function key does not work.

* Getting comfortable
** CapsLock
Tweak /etc/default/keyboard to remap CapsLock as secondary
Control, then in a TTY:

** apt install (1/n)
git greybird-gtk-theme elementary-xfce-icon-theme emacs

git suggests git-doc: why of course, good idea!

emacs suggests emacs-common-non-dfsg: right, what was that again?
Documentation, IIRC?  What does APT have to say?

#+BEGIN_EXAMPLE
$ apt show emacs-common-non-dfsg
Package: emacs-common-non-dfsg
State: not a real package (virtual)
N: Can't select candidate version from package emacs-common-non-dfsg as it has no candidate
N: Can't select versions from package 'emacs-common-non-dfsg' as it is purely virtual
N: No packages found
#+END_EXAMPLE

… What does https://packages.debian.org/emacs-common-non-dfsg say?

** Clone dotfiles
Allow external drives to be automounted: cf. Thunar section below.

Grab ssh keys from backup.  "Clone" (init, fetch, reset) dotfiles.

** Tweak dotfiles
Set EMAIL in .profile; copy .profile to .xsessionrc (AFAICT XFCE does
not read ~/.config/environment.d) to get PATHs.

In .bashrc, enable globstar and autocd, uncomment grep and ls aliases,
source personal .bash_prompt.

Fun fact!  git can guess user.email from $EMAIL and user.name from the
[[https://en.wikipedia.org/wiki/Gecos_field][GECOS field]].

Somewhat shorter than with BunsenLabs…

Write script to apply powertop advice.

Debian [[https://wiki.debian.org/LightDM#Enable_user_list][hides the list of users]] on the login screen; Bunsenlabs [[https://github.com/BunsenLabs/bunsen-configs/blob/9.6-1/lightdm.conf.d/50_bunsen.conf][enables
it]] and I kind of like it (fewer keystrokes, and a cute avatar).

                               ${SOMEWHERE}/firefox/firefox 1
    $ ln -s ${SOMEWHERE}/firefox/firefox ~/.local/bin/
    #+END_SRC

- paste backuped configuration into ~/.mozilla/firefox
