A couple questions inline.

It seems that you mean for netorkmanager to transition to initrc_t. 
Dbus_system_domain would transition from the system bus to 
networkmanager_t.  These don't seem at all alike.  Not sure which one 
you want, though dbus_system_domain() seems unlikely.

Why does sshd need to request a kernel module?

If you know it wants to list usbfs, why list all?

I'm not sure we want this.  Unconfined doesn't mean exempt on UBAC, 
MLS/MCS, etc.
