First, I absolutely do not want perfection to be the enemy of good here and
I'm interested in seeing the quick and easy fix slide in before freezes
prevent it so please interpret the following as an explanation of my
expectations and not a desire for immediate outcome for a resolution in my
bug report. I would however like to address the question of how desirable
flexibility in rescue mode is. We'll start with "desirable" is independent
of "what is actually implemented" as a desire can exist for a feature
without that feature existing as a feature existing is dependent on someone
implementing it but the desire itself is not. Now it becomes a question of
"what is desirable in Debian" and I certainly have an opinion on this
matter as a very happy user of Debian since 1995.

Debian is "The Universal Operating System" by its own definition. Universal
has an implicit definition of flexible. I'm surprised to see that offering
the user choices is not a widely agreed upon fundamental principle. My
expectation from the entire Debian ecosystem is that it will let me make
choices when possible even if those choices perhaps are wrong or may lead
to unwanted outcomes. This is a critical part of being "universal."

I'd also like to point out that derivatives of Debian that are "on rails"
already exist, such as Ubuntu, and I believe also Mint, and if I was
interested in a system that was not "universal" I would be using one of
them instead. The very thing that makes Debian what it is, at least to me,
is the flexibility and that is absolutely my expectation for its behavior
from every part of it. So I really don't understand how asking the user
what subvolume to mount could be undesirable aside from the level of extra
effort involved in the implementation itself.

As always I greatly appreciate the work everyone puts into Debian. I'm
quite grateful to have such an excellent operating system I can rely on and
it has well earned its place as my default choice for Linux distributions
and a tool I can rely on when I'm in situations where I need a reliable
base to help me conquer possibly unreliable larger systems it is the base
of.

Cheers to all and thank you again.
