Not able to use wpa_supplicant after `emerge --depclean -a`

[znavko]

Hello, dear developers and Funtoo Forums users! I see the network stop working with wpa_supplicant cause rfkill was deleted. I only did this:

# eix-sync
# emerge -uDN @world
# emerge --depclean -a
# emerge --update --newuse --deep @world
# emerge --depclean -a
# reboot
""" No network
# whereis rfkill
rfkill:
""" I use networkmanager

Sure I installed rfkill now. But why it was lost?

rfkill is provided by util-linux in recent versions which is part of @system. There may be an oversight somewhere that lost the dependency on the stand-alone version that is needed if you have sys-apps/util-linux-2.29.2-r1. just my thoughts :)

Thank you! Plus to this question my searchings are why NetworkManager can work with wlan0, but wpa_supplicant says "wlan0 blocked" and needs `rfkill unblock wifi` ?

How to use wlan0 not installing rfkill? How NetworkManager can?
