Dont know the meaning of sestatus's report

[Patrick Chiang]

Dear all,

I'm new to SELinux,
hopefully my question is not a FAQ,
I've googled around for a while but still no clues at all.

while I run sestatus, I found these messages...

allow_ypbind            inactive
httpd_disable_trans     inactive
httpd_enable_cgi        active
httpd_enable_homedirs   active
httpd_ssi_exec          active
httpd_unified           active
named_disable_trans     inactive
named_write_master_zonesinactive

some of them are easy to understand, 
but the rest phrases, such as named_disable_trans, httpd_unified,  are
rather difficult.
Does anybody know how to decode these?

TIA,

Patrick
