Comment # 62 on bug 816388 from kolA flash

Probably!
But test what happens if you put your Notebook/PC into standby/s2ram or
hibernate/s2disk. Afterwards the value will probably be 128, because s2ram and
s2disk will reset the value but boot.local doesn't become active when waking
from s2ram/s2disk.
For handling s2ram/s2disk use the file /usr/lib/systemd/system-sleep/99hdparm
as described by me.

Nevertheless, this bug-report is now more about find a general strategy to fix
this issue for all openSUSE users.
E.g. keeping openSUSE from accessing the hdd every few seconds or setting the
hdparm/APM value to 192 or 254.
