I can't claim expertise or authority here, but intuitively 20% per
year seems excessive. I could easily be wrong.
My /boot partition has been 1GB for years, in line with the current
recommendations.
The "rescue" being twice the current "kernel" comes from actual numbers
from a fully default "bare metal" install done late this past April,
rounded up.
10+ years ago, I did the original fully default install on the same
desktop. It was said a few times in this thread that Fedora defaults to
keeping 3 old "kernels" when the "kernel" is patched. So after several
weekly patches, I'd have the current "kernel", 3 old "kernels", and 1
"rescue". That adds up to current + 3 old + "rescue". "Rescue" is
twice current. So the total space is 6 times the then-current "kernel".
Over the intervening 10 years, in order to keep doing weekly patches and
semi-annual upgrades, I had to delete old "kernels" and reduce the
number of retained old "kernels" in the configuration file, eventually
to zero. I also had to delete the "rescue". So at the end of about 10
years, the space that at first could hold the equivalent of 6 "kernels"
could only hold one. That is about the same as saying the size of the
"kernel" now (well, in late April of this year) is about 6 times the
size of the "kernel" about 10 years ago. The math:
annual growth rate as a percent = 100 * ((overall growth ^ (1/years)) -
1) = 100 * ((6 ^ (1/10)) - 1) = 20% (rounded up).
Approximations and rounding were used along the way.
The only thing that I can think of that would throw the logic off
significantly is that 10 years ago, I had an nvidia graphics card and
the rpm fusion driver for it. Before doing the new install in late
April this year, the graphics card was removed, so no graphics driver.
That's the best I can do with the information I have.
