pxe_just_once is a global flag to Cobbler, which changes the way one of
the kickstart snippets works -- it unsets netboot-enabled when invoked
in the %post section. It still relies on the victim server netbooting in
the first place and issuing that snippet.

Now, you *could* make a change locally to run IPMI pxe when
netboot_enabled is set for each system, on sync, and then "un-run" it
(I'm not sure if there is an equivalent of turn off "pxe" mode) in the
%post snippet. If the latter doesn't exist (that is turning on pxe mode
is really a one-off, and will automatically disable on victim reboot),
then I think you're best off just using a trigger on sync?
