I'm aware of the kernel recognising securelevel having a value of -1, 0, 1
or 2 and above but are there any plans for implementing something more than
this ?

It has been suggested that IP Filter disallow changes to filter rules if
securelevel is set to some level...(I think 3 was the suggestion).

However, before doing this, I want to poll people on whether they think
three is appropriate, or should 10 be used (say) as a synonym for
"firewall security level".

Thoughts ?
