Some months ago when I inquired about adding @booted_kernel,
the sense I got from the discussion was that the whole idea
of magic symlinks had some strong opposition (which probably
in part explained the change from per-mount to sysctl-global,
as a way of encouraging the feature to just fade away :) .
Did I get the wrong sense from that earlier discussion? Or is
there a good link to the archives that could be supplied to
represent the contra-magic-symlink position adequately?
