You can set the kernel parameter with R:: in addkcmdline before the OS deployment, so during the OS deployment the kernel parameter will be added to boot parameter persistently.
But note that R:: means for boot only. If you want a kernel parameter to be applied for both os deployment and booting, the kernel parameter needs be specified twice in the addkcmdline: one with R::, one without.
Thanks
Best Regards

Hi,
I have a node that uses an old CCISS controller that has no driver
support in EL7.2 any more. SO I am setting
hpsa.hpsa_allow_any=1 and hpsa.hpsa_simple_mode=1 and anaconda enables
the controller and installs the operating system.
Unfortunately, after the final reboot, the kernel parameters are not set
permanently. So I have added them a second time with the R:: prefix, but
this does not help. How can I make them permanent without manually added
them in a postscript?
Additionally, I have seen that addkcmdline set in node, group and
osimage are not merged. Instead node ranks out group, and group ranks
out osimage. Is this intended or can I somehow enable combining all
addkcmdline settings somehow?
Markus
