Package: cpufreqd
Version: 2.4.2-1
Followup-For: Bug #583663
As this bug (or rather feature request) is still open, and I ran into
this issue on my machine, I decided to chime in. I think it would
indeed be nice if cpufreqd could figure out the modules to load by
itself, as cpufrequtils' init script loadcpufreq already does. Like
Petter Reinholdtsen, I don't think depending on cpufrequtils is
wrong, and I'd like to suggest the following potential solution for
this bug:
1) Promote the "Suggests: cpufrequtils" to a Recommends.
2) Apply the patch initially provided for this bug report (adding
"Should-Start: loadcpufreq") to the LSB headers of cpufreqd's init
script).
This way, cpufreqd would work out of the box without manually telling
it which modules to load, and code duplication for module loading is
avoided. Users can still decide they don't want cpufrequtils and
configure the modules to load in /etc/default/cpufreqd manually.
Looking at the size and dependencies of the cpufrequtils package, I
don't see a reason why it should not be installed as a dependency of
cpufreqd in all but unusual configurations, making it a perfect fit
for "Recommends".
