I know that the boot mechanism changed a bit for F30, but I'm not sure where to look to identify the cause of this problem. It doesn't seem to be the same issue as described in BZ 1652806. >> >> Steve > > It can be tricky for the grubby scripts to deduce which kernel was > *really* the last one, especially if you've been hand-editing kernel > entries or adding them manually, well, there might be debris. > > /boog/grub/ has gotten *fascinating* Perhaps you can back up the > system, and then delete *all* the extraneous kernels, to reset any > confused default tracking mechanism in place?. "Fascinating" is a good word for it. I tried reading through the various scripts. They are a twisty little maze of passages. :-) The problem has suddenly gone away. I just installed kernel 5.0.11, and this time it correctly became the default. I'm not sure what fixed my issue, but I can think of two possibilities. 1) Prior to installing 5.0.11, I did run the grub2-install command, as mentioned in the Common_F30_bugs wiki page. Perhaps that helped, even though my symptoms were very different. 2) Also, installing 5.0.11 obsoleted the last of the F29 kernels on my machine. Now there are only F30 kernels in /boot. I'll keep an eye on it, but for now I'm good.
