Bug 709151

As a temporary fix, you can (as root), do this:
 touch /etc/rc.d/init.d/dhcpd
 chmod a+x /etc/rc.d/init.d/dhcpd
 cobbler sync

Only a workaround until this bug is addressed.

Still not fixed in FC16 cobbler-2.0.11-3.fc16.noarch

Created attachment 561235 [details]
dummy /etc/init.d/dhcpd that invokes /bin/systemctl

better workaround -- actually invokes systemctl for dhcpd.service

Sorry about late answer...

I was using the workaround Alan proposed but I should say if using SELinux the init script needs to be properly labelled:

chcon system_u:object_r:dhcpd_initrc_exec_t:s0 /etc/rc.d/init.d/dhcpd

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

*** Bug 743868 has been marked as a duplicate of this bug. ***

This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

actually, you can fix this quite easily.

create a temp folder

mkdir ~/123
cd /usr/lib/python2.7/site-packages/cobbler/modules/
cp sync_post_restart_services.py ~/123/
mv sync_post_restart_services.py sync_post_restart_services.py.original
mv sync_post_restart_services.pyo sync_post_restart_services.pyo.original
mv sync_post_restart_services.pyc sync_post_restart_services.pyc.original

cd ~/123
vim sync_post_restart_services.py
*EDIT Line number 44
==>> FROM rc = utils.subprocess_call(logger,"/etc/rc.d/init.d/dhcpd restart", shell=True)
==>> TO   rc = utils.subprocess_call(logger,"/bin/systemctl restart dhcpd", shell=True)
then save


Now compile files:

python -m compileall *
python -O -m compileall *

ls command should show you that you got 3 new proper files:
[root@space01 123]# ls
sync_post_restart_services.py  sync_post_restart_services.pyc  sync_post_restart_services.pyo

now copy them over to where they should be:

cd /usr/lib/python2.7/site-packages/cobbler/modules/
cp ~/123/* .

Now restart cobblerd

[root@space01 123]# systemctl restart cobblerd
[root@space01 123]# cobbler sync
