How to make persistent changes in the boot cmdline used by GRUB2 in TrueNAS Scale?

[ldhaynesnc]

First time posting but long time user of FreeNAS.

I have deployed Scale on a server without a VGA port and so I am using an HDMI port as the console. At a certain point in the boot, console messages cease and the keyboard is not responsive. Console functionality can be established by specifying HDMI settings in the kernel boot cmdline. I am able to manually edit the boot cmdline from the GRUB2 initial prompt and all is good until the next reboot. On a Debian/Ubuntu image, I would append the HDMI settings onto the GRUB_CMDLINE_LINUX_DEFAULT directive in the in the GRUB config file (/etc/default/grub) then run update-grub to make the change permanent. That method does not work with Scale and so my question is what is the proper way for Scale?

Thanks in advance for all suggestions.

I don't think this capability exists yet in the alpha. See https://www.truenas.com/community/threads/scale-needs-an-equivalent-of-tunables-from-core.90379/.

As far as I can see in the code, it hasn't been done yet, and I haven't submitted a JIRA either

I have the same issue re: HDMI console. Safe to assume this issue isn't yet addressed in the beta?
