(Everyone), please keep the explicit "Proposal owners"/"other
developers"/"release engineering"/"policies and guidelines" split.  Other
contributors *need* to know what they are being asked to do by your Change.

* Policies and guidelines:
>
** Adjust packaging guidelines to mention migration of cron jobs to timer
> units for packages that already depend on systemd
>

Last time this was discussed in
http://meetbot.fedoraproject.org/fedora-meeting/2013-02-06/fesco.2013-02-06-18.00.log.html,
there were concerns about "confusion of users/admins", specifically
referring to the disabling a .service / disabling a .socket duality.  So we
will need packaging guidelines not only for the migration, but for the
timer units themselves.

(From the Change page:)

> Administrators will have better time trigger in units compared to cron
> jobs like for example when administrator stops a service/daemon the timer
> unit will stop as well etc.

This would also seem to require detailed packaging guidelines for the timer
units.

* Fix spec files in packages that are not applicable for migration [Fix Cron
> Dependency Tracking Bug 2]
> * Review and migrate if applicable cron jobs shipped in packages that
> already
> depend on systemd [Timer Migration Tracking Bug 3]

How many packages (at least an of magnitude) are we talking about?  Is it
the 16+3 that are currently blocking the tracker bugs?
