The hostname needs to be in quotes. Change this up in your
dhcp.template to have quotes around them.
Many thanks, that hits the nail on the head and fixes the problem and
addresses the points raised by Jeff. Thus the dhcp.template file should
be updated to fix this in git.
The relevant section of my dhcp.template (slightly modified from the
default) looked like this and give raise to my perception of a bug.
#for dhcp_tag in $dhcp_tags.keys():
## group could be subnet if your dhcp tags line up with your subnets
## or really any valid dhcpd.conf construct ... if you only use the
## default dhcp tag in cobbler, the group block can be deleted for a

# group for Cobbler DHCP tag: $dhcp_tag
group {
#for mac in $dhcp_tags[$dhcp_tag].keys():
#set iface = $dhcp_tags[$dhcp_tag][$mac]
host $iface.name {
hardware ethernet $mac;
#if $iface.ip_address:
fixed-address $iface.ip_address;
#end if
#if $iface.hostname:
option host-name $iface.hostname;
#end if
#if $iface.subnet:
option subnet-mask $iface.subnet;
#end if

}
#end for
}
#end for
All the best,

Something else seems to be wrong. I don't think that patch solves the
root of the problem. Say you have donkey11.site1.int
<http://donkey11.site1.int>,
donkey11.site2.int <http://donkey11.site2.int>, and
donkey11.site3.int <http://donkey11.site3.int>, etc... Your patch
breaks
that type of setup. We use system name and hostname == fully qualified
domain name and it works like a champ.
Out of curiosity, without your patch, does this work:
cobbler system rename --name donkey11 --newname
donkey11.somewhere.com <http://donkey11.somewhere.com>
&& cobbler sync
Are you using the default /etc/cobbler/dhcp.template? It looks like
the template is doing something it shouldn't and generating a bogus
dhcpd.conf. If you're not using a default template, can you paste it
somewhere that we could see it?
