Ok usermod and useradd do the setfilecon calls. One thing you might want to
do is transition to useradd_t.
usermanage_domtrans_useradd(pwrecoverd_t)
User add currently has these two exceptions.
domain_obj_id_change_exemption(useradd_t)
domain_system_change_exemption(useradd_t)
It looks like you might need both if you want pwrecoveryd_t to do this.
