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/ >How-To-Repeat: as above >Fix: >Release-Note: >Audit-Trail: >Unformatted:
