In general, it's not very usuful to repeat the unit name as the description.
Especially when the word is a common name and if somebody doesn't understand
the meaning immediately, they are not going to gain anything from the
repeat either, e.g. "halt", "swap".
In the status-unit-format=combined output parentheses are used around
Description, so avoid using parenthesis in the Description itself.
Since commit 19f8d03783 'timer: order OnCalendar units after
timer-sync.target if DefaultDependencies=no' timers might get a
dependency on time-sync.target, which does not really belong in early
boot. If ntp is enabled, time-sync.target might be delayed until a
network connection is established.
It turns out that majority of timer units found in the wild do not
need to be started in early boot. Out of the timer units available in
Fedora 21, only systemd-readahead-done.timer and mdadm-last-resort@.timer
should be started early, but they both have DefaultDependencies=no,
so are not part of timers.target anyway. All the rest look like they
will be fine with being started a bit later (and the majority even
much later, since they run daily or weekly).
Let timers.target be pulled in by basic.target, but without the
temporal dependency. This means timer units are started on a "best
effort" schedule.
