Makes sense.

Seems reasonable to drop the
if [ ! -e /sys/kernel/uevent_helper ]; then
echo "udev requires hotplug support, not started."
return 1
fi
checks from postinst and the udev SysV init script.
udev has been switched over to use the netlink based interface for
communicating with the kernel a long time ago.
Marco, at least I don't see a good reason to keep them. Do you agree?

I don't think they have any plans to change that. But CCed the kernel
team just in case.
Just curious, was this triggered by [1]. Usually CONFIG_UEVENT_HELPER is
set (at least by distros for compat reasons) and contains "".
