I'd personally not like to see SMACK appear in a capability name. No
offense Casey, but SMACK may be displaced with YAMAC (*) someday, and
I'd hate to have wasted a capability on it. Using CAP_MAC_OVERRIDE makes
sense to me - even if its not (yet/ever) honored by all MAC LSMs.

I do have a question about whether one capability is sufficient in
general for MAC. Looking at the:

  http://wt.xpilot.org/publications/posix.1e/download.html

last draft, there are no less than 5 capabilities (p173) allocated for
MAC. Presumably there was a good reason for 5 and not 1 back then -
could you summarize what is different now?

Thanks

Andrew
