>Description:
This applies to any installation env (VirtualBox, other hardware platforms).
On VirtualBox, I selected powerd service during install, but at boot time there
was an error msg:
starting powerd
powerd lookup freq: No such file or directory
/etc/rc: WARNING failed to start powerd
Disabling powerd in /etc/rc.conf to get rid of the error message is a fix, but
not a solution to a problem.
Making a statement that in VirtualBox powerd doesn't work because the guest
OS can not control the frequency of the host CPU is true, but is not a solution
as well.
The solution is to NOT offer bugus/invalid services for installation env, real
or virtual.
Bsdinstall can discover this condition with checking for lack of
sysctl -a | grep dev.cpu.0.freq
sysctl -a | grep dev.cpu.0.freq_levels
in /usr/libexec/bsdinstall/services,
exactly as it does (in powerd.c) with
if (sysctlnametomib("dev.cpu.0.freq", freq_mib, &len))
err(1, "lookup freq");
...
if (sysctlnametomib("dev.cpu.0.freq_levels", levels_mib, &len))
err(1, "lookup freq_levels");
in /usr/sbin/powerd (via /etc/rc.d/powerd).
Bsdinstall already does similar checks for other features, see:
$ grep -ir sysctl /usr/libexec/bsdinstall/
