We would need to either have a separate config entry, that can easily
get out of sync with the actual configured values, or parse all possible
ways to set this, e.g., modprobe configs, which isn't too nice.

With a few trade-offs/limitations one could probably work around that,
but IMO it can be a bit too much hassle for something that one normally
changes only once or twice (or once this change is in, probably never
for new setups), so for now I'd keep this manual.
