So as far as the kern's concerned, "new-host" is the hostname.

You could have hit a combination of dhcp settings on the dhcp server
and dhclient settings on the laptop that forces your laptop to get a
hostname from the dhcp server. Anyway, I think that you said in
another post that this is happening before the network comes up; so
this isn't it...
I vaguely remember (but could be misremembering!) someone reporting
something similar on Fedora where GNOME/GDM was setting the hostname.
You could check whether this is the issue by appending "text" to the
grub "linux" line.
BTW, where are you seeing the new hostname?
