i think i have found the cause of my boot problems and also one or two bugs in
first one that is not so critical but still different compared to how fedora28
version of fedora-arm-image-installer worked and is related to --resizefs
in fedora28 this did the right thing, in fedora29 it doesn't work.
it appears to do something but my guess is that it tries to resize wrong
partition or similar.
end result is no resizing of root partition.
second one is the important one.
specifying --norootpass results in an image totally broken with a lot of
services errors with "Unknown username" (if you turn on systemd journal
to serial console) and then boot is stuck in an endless loop.
i'm guessing fedora-arm-image-installer incorrectly modifies some files
with above two changes i have now successfully 4 sd cards for my 4 odroid hc2
that all boot properly on first try with no long boot delay.
so i think i can say it is repeatable.
And from your bug report, which you don't reference here, you're using
2.5 and I believe this has now all been fixed in a now stable 2.8
