I agree, but currently the output list, printconfig and those are heavily
formatted in the kernel, so I was just looking for the easy way out as a
temporate solution. However, I intend to pass the whole configuration to userland, not just the
label, and let the tools format it there, as I see to this point see no reason
for it to be in the kernel.
