##	Create a file type used for init scripts.  It can not be

##	used in conjunction with init_script_domain(). These

##	script files are typically stored in the /etc/init.d directory.

##	

##	

##	Typically this is used to constrain what services an

##	admin can start/stop.  For example, a policy writer may want

##	to constrain a web administrator to only being able to

##	restart the web server, not other services.  This special type

##	will help address that goal.

##	

##	

##	This also makes the type usable for files; thus an

##	explicit call to files_type() is redundant.

## <summary>

##	Inherit and use file descriptors from init.

## </summary>

## <desc>

##	

##	Allow the specified domain to inherit file

##	descriptors from the init program (process ID 1).

##	Typically the only file descriptors to be

##	inherited from init are for the console.

##	This does not allow the domain any access to

##	the object to which the file descriptors references.

##	

##	

##	Related interfaces:

##	

##	

##		
init_dontaudit_use_fds()

##		
term_dontaudit_use_console()

##		
term_use_console()

##	

##	

##	Example usage:

##	

##	

##	init_use_fds(mydomain_t)

##	term_use_console(mydomain_t)

##	

##	

##	Normally, processes that can inherit these file

##	descriptors (usually services) write messages to the

##	system log instead of writing to the console.

##	Therefore, in many cases, this access should

##	dontaudited instead.

##	

##	

##	Example dontaudit usage:

##	

##	

##	init_dontaudit_use_fds(mydomain_t)

##	term_dontaudit_use_console(mydomain_t)
