I use tlp and tlp-rdw on my laptop to manage power/performances modes, and enable/disable the WiFi radio. With F35 this was working fine.
On Friday I did an in-place upgrade to F36 Beta, and this morning I realized that two default services that I had masked (so that tlp could do its job) were unmasked during the upgrade.
Specifically, power-profiles-daemon.service and systemd-rfkill.service were unmasked. Since masking creates a symlink (to /dev/null) in /etc/systemd/system, which is a user-managed directory, I was quite surprised that the upgrade removed the symlinks.
