In the previous thread at:

https://mailman.bitfolk.com/mailman/hyperkitty/list/users@mailman.bitfolk.com/message/L7ZPUTZ3SXZ6KR2UGY5XWZHCCLWFVJZ7/

we had got as far as working out that it's grub2-tools which
triggered this, but although you can disable this by putting

Yes, sorry, read it too quickly.

GRUB_ENABLE_BLSCFG=false

in /etc/default/grub and doing

# grub2-mkconfig -o /boot/grub2/grub.cfg

it's unclear to me whether the system continues then updating
grub.cfg on new kernel install or not.

I suppose my most pressing questions are:

- Does the above revert this configuration?

Yes is does, but...

- Does it stay reverted or does every update of grub2-tools put
BLSCFG back even if GRUB_ENABLE_BLSCFG=false is set?

It appears up or downgrading reverts this back to 'true' every time, which is really quite annoying.

- Does grub.cfg keep getting updated properly on new kernel
installs?

As long as the /etc/default/grub has the correct settings, yes. But see above.

According to the rpmspec of grub2-tools, the file shouldn't be replaced *1:

%files
%config(noreplace) %ghost %attr(0644, root, root) %verify(not md5 size link mtime) "/etc/default/grub"

That fles appears to be in all versions of the package with the same line. So I suspect it's a bug somewhere, because there's a .rpmsave file:

[root@localhost default]# ll
total 12
-rw-r--r--. 1 root root 322 Jul 10 02:23 grub
-rw-r--r--. 1 root root 323 Jul 10 02:23 grub.rpmsave

I think it could be the %ghost directive, which may just be replacing the file. *2

But that's about as far as I'm going to dig into this.
