Chromium Windows Cross Compile - fuse device error

[Daniel B]

I'm trying to cross-compile Chromium for Windows on an Ubuntu machine.
My builder is a Pod that starts from a self-hosted Github Runner (on our EKS).

When I reach the step to run gclient sync, I get an error:

fuse: device not found, try 'modprobe fuse' first

It is fixed by adding privileged: true but it's too open.
I tried:

securityContext:
capabilities:
add:
- SYS_ADMIN

But it just gives the same error.

Can anyone point to an easier fix? It only happens for Windows builds where I add:

echo "target_os = ['win']" >> .gclient

And then run gclient sync.

Thanks
