+ When systemd-hostnamed is used it is strongly recommended to
+ install nss-myhostname to ensure that in a world of
+ dynamically changing hostnames the hostname stays resolveable
+ under all circumstances. In fact, systemd-hostnamed will warn
+ if nss-myhostname is not installed. Packagers are encouraged to
+ add a dependency on nss-myhostname to the package that
+ includes systemd-hostnamed.
+
WARNINGS:
systemd will warn you during boot if /etc/mtab is not a
symlink to /proc/mounts. Please ensure that /etc/mtab is a
about this, since this kind of file system setup is not really
supported anymore by the basic set of Linux OS components.
