‘apm’ is a well-known, old power management command provided by the
apmd package in Debian and Ubuntu. Modern systems use ACPI instead and it seems that at least Debian and Ubuntu kernels no longer enable APM support. Having been an apm user in the past, my knee-jerk reaction was to -1 this, but I suspect these days there are far more ‘atom package manager’ users than ‘advanced power management’ users.
While I don’t like collisions of this nature, I’ll give a +1 for the reasons stated above.
