I don't know the details for other dhcp implementations, but systemd-networkd will use the dchp-provided "transient" hostname if the "static" hostname is unset or set to "localhost". Note that this is done dynamically, i.e. the hostname from dhcp is never stored in /etc/hostname. > Sorry, Radek. I can't parse that.

If those other implementations behave like systemd-networkd, then Radek's comment makes perfect sense ;) Zbyszek _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org
