Debian Jessie désactiver la session graphique gnome GDM au démarrage
Les joies de systemd.
En théorie, il faudrait faire :
systemctl disable gdm systemctl disable gdm3
Mais ça ne marche pas.
Solution
unlink /lib/systemd/system/gdm3.service
Pour réactiver la session graphique au boot
ln -s /lib/systemd/system/gdm.service /lib/systemd/system/gdm3.service

Quand 2 paquets Debian fournissent un fichier même nom, même arborescence.
Deux paquets .deb (apt:moreutils et apt:parallel) fournissent un fichier /usr/bin/parallel
apt-file search /usr/bin/parallel |grep '/usr/bin/parallel$'
moreutils: /usr/bin/parallel parallel: /usr/bin/parallel
apt-get update && apt-get install moreutils ls -ld $(dpkg -L moreutils | sed -e '1d') | grep '^-'|awk '{print $9}' | grep -v parallel | cpio -ov --format=ustar |gzip > moreutils.tar.gz apt-get remove moreutils cd / tar xzvf moreutils.tar.gz -C '/' apt-get install parallel
C'est pour l'exemple avec cpio. Mais c'est pas très propre. Il contraindrait d'utiliser dpkg-divert
