default_type limitations

The default_type functionality is too limited because it assumes that all login programs associate the same type with a given role

This is not the case

For example:

default_type for local_login: joe.role:joe.type
default_type for sshd: joe.role:joe_ssh_server.type
default_type for cockpit joe.role:joe_cockpit_bridge.type

etc

So pam_selinux "select_context" can only support a single login program due to this

I do not understand why default_type is needed in the first place. The contexts/users/ file is more specific:

/etc/selinux/TYPE/contexts/users/joe.user:
sys.role:login.type:s0 joe.role:joe.type:s0 joe1.role:joe1.type:s0
sys.role:sshd.type:s0 joe.role:joe_ssh_server.type:s0 joe1.role:joe1_ssh_server.type:s0
sys.role:cockpit_session.subj:s0 joe.role:joe_cockpit_bridge.type:s0 joe1:joe1_cockpit_bridge.type:s0

ie. its already specified that for example joe1.type is default type for joe1.role for local_login and that joe1_ssh_server.type is default type for joe1.role for sshd

So unless i am overlooking something, the default_type file is redundant and it actually adds an extra file to configure
