Ok, so you don't mind being passed in fs_freq and fs_passno as last fields
of --mount option.
In that case, Dave can you please also post a patch to modify dracut to
parse these fields and use default of "0 0" only if use did not pass those.
Also please modify dracut man page and mention that one can pass in
fs_freq and fs_passno as last options.
Dave, in the changelog of this patch, can we also please mention that
why we need to set passno explicitly. We can mention that default is zero
and that means no fsck will be run. But we want to make sure fsck is
run before we try to save dump on filesystem.
Thanks
Vivek
