But the thing is this: /dev/sda7 is another linux OS in this case and no-one told the freakin' system to *mount* it ANYWHERE! So why is it being mounted at all? Knowing where something is is one thing, sticking your dick into it without being told to is something else.
This has been bothering me too lately, mostly though with ESPs on multiboot systems, sticking the ESP in /efi if no entry for ESP exists in /etc/fstab. One way to deal with it generally is to create a noauto fstab entry for it. Ben T. Fender composed on 2024-01-26 11:39 (UTC-0500):

That's a lot of wasted disk space.
