Firmware with CGD on root - Can't read iwn firmware

output of uname -a:
NetBSD host 9.2 NetBSD 9.2 (GENERIC) #0: Wed May 12 13:15:55 UTC 2021 mkrepo@mkrepo.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64

Hello all,
I've recently reinstalled NetBSD on my Lenovo ThinkPad T430, this time, trying out root on CGD with NetBSD 9.
It works perfectly fine, except when it comes to loading my wireless card's firmware, found at /libdata/firmware/if_iwn/iwlwifi-6000g2a-5.ucode , which I assume is provided by the sysutils/iwn-firmware package.

Here's the output of dmesg:
[ 24.301700] iwn0: autoconfiguration error: could not get firmware handle iwlwifi-6000g2a-5.ucode [ 24.301700] iwn0: autoconfiguration error: could not read firmware [ 24.411777] iwn0: cannot assign link-local address

I genuinely don't know how to figure this out, which is why I've started this discussion. Root on CGD is not important to me, so I could just not use it, but where's the fun in that?
I'm guessing I'd need to somehow include it in the ramdisk created with cgdroot.kmod , or it could be as simple as a misconfigured package :( .

The initial ram disk mounts the encrypted root on /altroot and then chroots into it. The kernel however needs to be instructed to look for firmware in the real path, which means prepending/altroot to the standard firmware path(s).
Add this line to /etc/sysctl.conf:

hw.firmware.path=/altroot/libdata/firmware:/altroot/usr/libdata/firmware:/altroot/usr/pkg/libdata/firmware

JuvenalUrbino This worked perfectly, I cannot thank you enough!
