postmarketos-ui-i3wm|mate.post-deinstall:
Contains removal of file "61-autologin.conf"|"65-autologin.conf".
However, this file is removed by apk automatically unpon
deinstallation.
postmarketos-ui-i3wm|mate|xfce4.pre-deinstall:
Contains disabling service "lightdm". Removing display manager service
upon deinstallation isn't done by other UIs either. It can lead to
unexpected behaviour when installing another UI using lightdm and then
uninstall MATE UI.
Additionally
postmarketos-ui-i3wm.post-upgrade:
Removed postmarketos-ui-i3wm.post-upgrade and replaced it with a link to
postmarketos-ui-i3wm.post-install, like it's done in MATE and Xfce4.
