[Message part 1 (text/plain, inline)]

Again, thanks for the consistent quick turn-around, lately.

Exactly.

Thanks to your close reading of the patch and your opinionated suggestions, we
were able to catch this

Of course. It would be kind of ridiculous to merge some random, only vaguely
related patch deep in the internals of the system, as part of a simple package
addendum.

We're not writing bills for the Senate here!

Whether or not the patch is valuable, I could learn a lot from any ensuing
discussion, so I might take up your idea to post separately.

Sounds clear to me!

However, for some reason, right now if 'search-auxiliary-file' is inside a
file-union, I'm getting ENOENT on the file somewhere:

    Backtrace:
               2 (primitive-load "/gnu/store/fk7mr923n47r7wj7xqlfmh80jc5?")

Running `stat <path>` from the command line on the offending path succeeds as
expected, and moving the 'search-auxiliary-file' out of the file-union and
into the package inputs lets the build proceed.

I'm stumped. Attached is the package definition, for reference.

Sure. I'm mostly just way out of my depth here, getting sent on deep
rabbit-holes every time you respond give me some feedback to chew on. :P

Definitely down for some stylistic improvements. Let me know!

Hope you got some nice relaxation time in!
