Something else seems to be wrong. I don't think that patch solves the root of the problem. Say you have donkey11.site1.int, donkey11.site2.int, and 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 && 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? -- Jeff Schroeder Don't drink and derive, alcohol and analysis don't mix. http://www.digitalprognosis.com _______________________________________________ cobbler mailing list [email protected] https://fedorahosted.org/mailman/listinfo/cobbler
