turnstile en vez de elogind

turnstile solo crea XDG_RUNTIME_DIR (backend none, sin exportar el bus de
D-Bus, que lo abre .xinitrc). Xorg ya arranca como root con Xorg.wrap y la
tapa y los botones los lleva acpid, así que elogind sobraba. Fuera su
logind.conf.d.

+## Without elogind
+
+elogind is systemd's logind on its own, and it is not needed here:
+
+- `XDG_RUNTIME_DIR` (`/run/user/UID`) is created by turnstile at login
+  (`sistema/etc/turnstile/turnstiled.conf`: only that, no user services).
+- Xorg runs as root through `Xorg.wrap` (`needs_root_rights = yes` in
+  `/etc/X11/Xwrapper.config`, shipped by Void).
+- The lid and the power and suspend buttons are handled by acpid, which
+  calls `zzz`. Power off and reboot are runit's.
+- Devices (sound, video, input, bluetooth) are reached through the user's
+  groups, not through the ACLs elogind gave the active session.
+
+What stops working: mounting disks from a file manager (udisks2 asks polkit
+for an active session, and there is none). USB sticks are mounted by
+`automontaje`.
