Force network-manager not to send the hostname
Added by Lukas Zapletal almost 10 years ago.
Updated about 8 years ago.
Description
It looks like NM is still sending the hostname, which is bad thing for DHCP (a conflict with dracut can occur).
Make sure NM is configured NOT to send the DHCP client hostname:
gconftool-2 --type bool --set /system/networking/connections/<NUM>/ipv4/dhcp-send-hostname true

Backport to 0.6.
Here is a snippet where we see that dhclient was started with different hostnames, this can lead to DHCP conflicts eventually:
3024 tty1 Ssl+ 0:00 ruby /usr/bin/discover-host.rb
3049 ? Ss 0:00 /sbin/dhclient -H localhost -1 -q -lf /var/lib/dhclient/dhclient--eno1.lease -pf /var/run/dhclient-eno1.pid eno1
3162 ? Ss 0:00 /sbin/dhclient -H localhost -1 -q -lf /var/lib/dhclient/dhclient--eno2.lease -pf /var/run/dhclient-eno2.pid eno2
