Merci beaucoup c'est rassurant !
Normalement :
Any system running systemd should have /etc/os-release, which is specified as part of systemd. Some systems without systemd might have it too (e.g. Debian 8 where systemd is optional but /etc/os-release is installed in all cases).
According to the specification, all fields are optional, and some have defaults ("Linux" for NAME and PRETTY_NAME).
Je me suis donc permis de modifier le
PRETTY_NAME ça me permet d'avoir le bon nom dans les paramètres (à propos).
Après avoir redemarré (pour vérifier) ça fonctionne bien !
Par ailleurs lsb_release -a donne bien les bonnes informations
# lsb_release -a

J'ai aussi aperçu que ce fichier "/etc/os-release" n'allait pas être maintenu (source ::

One of the new configuration files systemd introduced is /etc/os-release. It replaces the multitude of per-distribution release files[1] with a single one.
Yesterday
we decided to drop support for systems lacking /etc/os-release in systemd since recently the majority of the big distributions adopted /etc/os-release and many small ones did, too[2]. It's our hope that by dropping support for non-compliant distributions we gently put some pressure on the remaining hold-outs to adopt this scheme as well.
[1] Yes, multitude, there's at least: /etc/redhat-release, /etc/SuSE-release, /etc/debian_version, /etc/arch-release, /etc/gentoo-release, /etc/slackware-version, /etc/frugalware-release, /etc/altlinux-release, /etc/mandriva-release, /etc/meego-release, /etc/angstrom-version, /etc/mageia-release. And some distributions even have multiple, for example Fedora has already four different files.
[2] To our knowledge at least OpenSUSE, Fedora, ArchLinux, Angstrom, Frugalware have adopted this. (This list is not comprehensive, there are probably more.)
