The procedure outlined did not work for me on my CentOS 7 box. Here
are some additions:
1) networking in rescue environment
The link describing how to enable networking is only available to
those paying for support.
I fumbled about in nmtui (Network Manager Text User Interface) until
it worked.
2) the permanent ESP isn't mounted
For updating the *.efi files (the main point of the exercise) the ESP
must be mounted on /boot/efi.
After the chroot:
If you have a separate /boot partition:
mount /boot
(I see no point in a /boot partition but many people have them.)
If you have a separate /var partition:
mount /var
etc...
Mount the ESP:
mount /boot/efi
Check that it is the partition that you want (/dev/sda1 in my
case).
Only then can you do the yum stuff.
================
Since I didn't do (2), I had to manually move things that landed in
/boot/efi (a directory and intended mount-point) to /boot/efi (the
filesystem).
On the next boot, SELINUX was upset and spent some time relabelling
things.
Seems to be working now.
================
I expect that this disaster is going to be fixed really quickly. So
I'm going to be lazy and not lock down the downgraded versions.
Instead, I will refrain from updating things until I hear of fixed
packages being available.
