The boot partition has been big enough for over 10 years, including the time I've had 4 kernels + 1 rescue kernel (since late last year). I'm puzzled about how the /boot partition is now too small. Has the kernel grown significantly?
In 10 years, very, very much. Fedora's splitting of kernels into multiple packages
complicates assessment of changes in size, but here is some raw data showing the
general trend from:

These are from an old Athlon that I stopped using Fedora on several years ago that
you could compare to your current installed kernels:

Rather easier to see I collected a few months ago from Tumbleweed 20230331 64bit:

The apparent drop in sizes after 5.18.15 is from applying more effective compression.
This barely does justice for the total magnitude since 10 years ago, but it does
show there have been steadily increasing overall kernel sizes.
ok. Thank-you, Felix. It is interesting to know that kernel sizes have been growing.
Making my /boot bigger would be a good thing to do, but as discussed in the original thread, entails more difficulty and risk than is wise for me.
