I did a regular softrware update on my boot drive -- the SSD
at /dev/sdc1 -- and got this:
Configuration file '/etc/grub.d/10_linux'
==> Deleted (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** 10_linux (Y/I/N/O/D/Z) [default=N] ?
I did "D" but have no clue as to what is right here. After looking at it
for a few minutes and ending up no more enlightened than I was when I
started, I kept the default. The first line of the thing is
+# grub-mkconfig helper script.
It contains things such as
+# Default to disabling partition uuid support to maintian compatibility
with
+# older kernels.
+GRUB_DISABLE_LINUX_PARTUUID=${GRUB_DISABLE_LINUX_PARTUUID-true}
Ought I have let it install? It seems a bad idea, but that is totally a
guess.

10_linux is complex and smart and unlikely to be changed by a user.
I can only guess: You probably accidentally touched 10_linux.
You're probably MUCH better off with the new package maintainer's
version.

In that I did the same update on the other drive, running the same version
of Ubuntu, without getting the question, could I then simply copy the
10_linux from there into /etc/grub/10_linux on this drive? Or would that
break things?

I just did "md5sum /etc/grub.d/10_linux" on a dozen or so very
different systems and they were all identical leading me to
believe it is not customized per system and therefore copying
it should work fine.

And the file doesn't exist *at all* on the drive I have booted now.
Would there be a need to rerun update-grub after copying it over, do you
suppose?

Odd. I have it on laptops, desktops, servers, and virtual machines.
It's identical across i386, amd64, and multi-arch. They are all
currently Debian Buster - I had been testing Bullseye but my test
boxes are back to Buster until the next TDE stable ships.

Good idea.

The plot thickens: there *is* a file on this booted
drive, /etc/grub.d/10_linux.dpkg-dist, that has the same size -- 18151 --
and timestamp as /etc/grub.d/10_linux on the other drive. Might dpkg have
left it there in case I clutched my pearls, said, "What a fool I've been!"
and wished to install it after all? Is this normal dpkg behavior when one
decides under such circumstances to stick with the original version of
something?

Yep. That's exactly what happens for "config files" you choose not to
accept. This is not really a config file but you can edit it so it is
treated as a config file.
