In practice this is already the case... If uname() execution
fails, or we fail to parse the result, we won't pass the
4.9+ required check in NetBpfLoad, which is required on S+,
and mainline no longer supports anything <S anyway.
We don't require subversion as technically "4.9" (ie. 4.9.0)
is enough for almost all usecases, although in practice I would
expect there will always be an LTS subversion present.
