Yeah, that seems wrong. Loading firmware from initramfs is required
for some things, like disk drivers. Of course, depending on how it's
done, it's all after the SYSTEM_BOOTING phase, but ..
What we *might* do is to not allow it for the user-mode helper
fallback, but I think it's more likely that we'll just deprecate the
usermode helper fw loader entirely, so adding new error cases for it
seems pointless.
