Hey all, recently after switching to systemd boot hooks I noticed I have quite a few extra ttys that I am not sure how to turn off. Additionally the sys-devices-virtual-misc-rfkill.device and dev-rfkill.device takes quite a bit of time to start despite systemd-rfkill being masked and these services depending on systemd-rfkill. As per the wiki I believe tlp is supposed to take care of rfkill stuff.
systemctl status sys-devices-virtual-misc-rfkill.device:
