I've put the hdparm stuff in /etc/local.d:
$ cat /etc/local.d/hdparm.start
#!/bin/sh
for device in /sys/bus/scsi/devices/[012345]:0:0:0/block/*; do
hdparm -W1B254S241M254 /dev/$(basename $device)
done
Make it chmod +x.
Then install the gentoo integration packet for systemd which creates
the proper units on the fly during boot:
$ emerge -a sys-apps/gentoo-systemd-integration
After restart, you should see units started for each local.d script.
It's implemented as a systemd generator. To see how it works, look at
"equery f gentoo-systemd-integration" and have a look at the generator
files.
