The bool gets turned off in the reboot process. It solves almost all the
avc issues but a few remained which were solved with this policy file:
module mysystemd 1.0;
require {
type systemd_logind_t;
type var_yp_t;
type node_t;
type hi_reserved_port_t;
class udp_socket { name_bind bind create setopt node_bind };
class file { read open };
}
#============= systemd_logind_t ==============
allow systemd_logind_t hi_reserved_port_t:udp_socket name_bind;
allow systemd_logind_t node_t:udp_socket node_bind;
allow systemd_logind_t self:udp_socket { bind create setopt };
allow systemd_logind_t var_yp_t:file { read open };
We also need to do a systemctl restart autofs.service after boot up. We
use NIS and auto mounted home directories.
