yum-updateonboot with Systemd

Using yum-updateonboot with systemd on Fedora 15\16(Rawhide).

As yum-updateonboot is a service,
it calls both yum and creatrepo (with yum-plugin-local).
Can both yum and createrepo then be considered services
for the purposes of systemd?

Example:
/etc/systemd/system/systemd-user-sessions.service

[Unit]
Description=Permit User Sessions
After=local-fs.target remote-fs.target yum-updateonboot.service

---------

even with this, boot still continues after doing some work,
would adding "After=yum.service createrepo.service" be any benefit.
In allowing the whole yum-updateonboot  process to Complete!
