I Zdenek, lets say I have a directory /var/www/html (type httpd_t) which 
need to be served both by httpd and smbd (type smbd_t).

As I can not set two labels on such directory, I have an issue: if 
leaving type httpd_t, then smbd can not access it; if setting type 
smbd_t, then httpd can not access it.

Sure, one can use samba_export_all_ro and similar booleans for this 
specific case. However, what if no appropriate booleans exists for the 
two services I want to share the same data? Does seliux have special 
provisioning for settings some files/dirs as "shared between these 
domains, as if multiple labels were used" or one has to explicity allow 
the required access via a custom selinux policy (ie: by using 
audit2allow)?

Regards.
