user_t daemons(Re: mDNSResponder running in user_t)

[Yuichi Nakamura]

I found iiim(htt_server) is running also "user_t".
Daemon programs started using su runs as "user_t".

Transition like
initrc_t(initrc script)->su_exec_t->initrc_su_t(su)->user_t(daemon)
is happening.

I think su command or initscripts or daemon should be fixed.
