That is true if the bootup fails, but it's fairly common that we get the
machine up (at least to the point when we can dmesg), but the user wants
to report a problem. For that case, it's very nice if the dmesg log
contains as much information as possible.
So I don't think it's clear that pre-filtering is what we want, at all.
