How do I create an initial policy for a new app?

[Brian Ginn]

using the polgengui, i get an error that the type is unknown (see below).



I compared the generated files to /usr/share/selinux/devel/example.*

I can see that I need to add the initial type myapp2_t;



... there are some other differences.  For example:



Polgengui's myapp2.te:

corecmd_executable_file(pbrun_exec_t)



example.te:

domain_type(myapp_t)

domain_entry_file(myapp_t, myapp_exec_t)



Do these accomplish essentially the same thing?





Thanks,

Brian
