This patch is modifying the shutdown.sh script to not use SYSRQ when
performing power actions. SYSRQ has a similar effect to a hardware reset
button/power switch, which can be problematic after copying an image to
the disk (data loss) therefore, this patch is changing the script to use
soft power action via the poweroff and reboot commands.
SYSRQ was required before because the ironic-python-agent service was
running inside a docker container, but since we've moved it to run into
a chroot (when built with coreos) or on the ramdisk's OS (when built
with DIB) the SYSRQ actions are not needed anymore.
In many parts of Ironic we were considering the standby.{power_off,
reboot} methods of IPA to be soft actions, which they are not at
present. This patch is also fixing that assumption.

fixes:
|
|
- Stop using SYSRQ when performing the in-band reboot or power off
|
|
because it has a similar effect to a hardware reset button/power
|
|
switch and can be problematic on some hardware types. Instead,
|
|
reboot/power off the node via the "poweroff" and "reboot" commands
|
|
(soft power action).
