[$] Last-minute /boot boost for Fedora 43

Sudden increases in the size of Fedora's initramfs
files have prompted the project to fast-track a proposal to increase
the default size of the /boot partition for new installs of
Fedora 43 and later. The project has also walked back a few
changes that have contributed to larger initramfs files, but the
ever-increasing size of firmware means that the need for more room is
unavoidable. The Fedora Engineering Steering Council (FESCo) has
approved a last-minute change
just before the final freeze for Fedora 43 to increase the
default size of the /boot partition from 1GB to 2GB; this
will leave plenty of space for kernels and initramfs images if a user
is installing from scratch, but it is of no help for users upgrading
from Fedora 42.
