Unfortunately, I lost my boot drive due to hardware failure. In principle, there was no important data on there. However, now I am struggling to set everything back up, even though I thought knew the necessary steps.
The first step was to install the Kernel module for the device LEDs; the device is a Ugreen DXP 6800 Pro. This can be found on github (I cannot provide a link here) and worked perfectly last time.
However, I cannot remember how I got to the point where I was able to compile kernel modules. When I try it now, with a fresh install of TrueNAS Scale 24.10.2 or even using the same iso I used previously (24.10.1), I get:
make -C /lib/modules/6.6.44-production+truenas/build M=[REDACTED]
make[1]: Entering directory '/usr/src/linux-headers-6.6.44-production+truenas'
ERROR: Kernel configuration is invalid.
include/generated/autoconf.h or include/config/auto.conf are missing.
Run 'make oldconfig && make prepare' on kernel src to fix it.
make[2]: *** [/usr/src/linux-headers-6.6.44-production+truenas/Makefile:809: include/config/auto.conf] Error 1
make[1]: *** [Makefile:237: __sub-make] Error 2
make[1]: Leaving directory '/usr/src/linux-headers-6.6.44-production+truenas'
make: *** [Makefile:11: all] Error 2
Will put this in here though I get the impression you understand the implications of going outside of the guardrails put in place (no support):
If there’s a specific kernel module you need and a valid use case, maybe you should stick in a feature request to see if it can be included in a later release?
Thanks, but the problem is more general and this is only the first kernel module I need. I will later need to install others, which are not directly available.
I ran install-dev-tools, but it did not fix the issue. It also seems I had already run it at some point. Output:

If you’re anticipating this, it’s entirely possible that TrueNAS is not the OS for you. It’s an appliance, it’s not intended that users will be messing around with the software, and iX are more and more hardening it to prevent users from doing this. I’m not saying it’s impossible to do what you’re asking, but you’ll be very much working against the design of the system.
It’s only three kernel modules, so I think it is worth it. This issue is not even about anything related to these modules, it is about why I suddenly no longer can compile them. Or anything that would require the kernel source.
Because it’s appliance software. It makes no promise that it will behave like a typical Linux distro.
I suspect that iX doesn’t test the ability to compile kernel modules (or anything else for that matter) inside TrueNAS. Bending TrueNAS to your will here will be a drudge for, as you said yourself, “only three kernel modules”.
