Sufficiently impractical that it's not possible.

Wrong.

I can make any process survive an X shutdown, using an amazing tool called "tmux".

Why can't dnf do the same?

It's why openSUSE has spent a ton of resources, and a few bloody
noses, getting completely atomic updates working with Btrfs and
snapper, with very fine rollback capabilities.

You do not need atomic updates to install a signal handler for SIGHUP or SIGTERM. And maybe issue a setsid() call, beforehand.

This shouldn't be rocket science.
