dnf system-upgrade fails on some RPi4 due to system boot date that pre-
dates gpg key
We're still kinda kicking around ideas for "fixing" this, but I think
if push comes to shove, we'll wind up revoting or waiving it as not
practically fixable.
Not adding to the ticket (because "me too" is not useful there), but...
I think Fedora should include SOME type of "fake hwclock"-type thing for
systems with no RTC (make a systemd service depend on /dev/rtc not
existing?), as other RPi-targeted distros do. This isn't RPi-specific,
a number of the small boards have no RTC. I do typically add an RTC to
my Pis, but not always (for various reasons).
