audit rules placement

[Lev Stipakov]

Hello,

I have a rpm/deb package which includes audisp plugin. In order plugin 
to work, I need to permanently add audit rules. It seems that for 
Centos/RHEL 7 I need to put those into /etc/audit/rules.d/audit.rules 
and for Centos/RHEL6 (and probably Debian / Ubuntu?) it is 
/etc/audit/audit.rules.

I noticed however that at least on Centos 7 I could put my rules into 
/etc/audit/rules.d/plugin.rules and they will be picked on auditd 
restart and added to /etc/audit/audit.rules. This does not work on 
Debian 8 - even though it has ruled.d directory only rules from 
/rules.d/audit.rules are used.

Is there some kind of "official" guidance to where I should put my rules 
on Centos/RHEL/Debian/Ubuntu ?
