I have the waydroid module enabled which I suspect may somehow be related.
I started waydroid and closed it and then stated each of the writable files by running find /nix/store -perm -600 -a -not -type l -print -exec stat {} \;

(omitted many lines due to similarity and body limit)
Both timestamps seem to be around the time when I turn off my computer where
2022-07-14 22:42:03.620579605 is the time at which I shutdown by my computer last night (according to journal logs)
2022-07-01 22:08:27.489691977 is likely due to the old path getting garbage collected.
Also, opening waydroid seems to have had no effect. Does anyone know why this may be happening, and if it is intended?

Because python is very difficult to convince NOT to write to the directories where its source files are. It’s the primary offender on this that I hear about. This is one of the reasons nixos mounts the nix store as a read-only filesystem. Essentially any python process running with write permissions on the nix store could be doing this. If it’s a mutli-user installation, that would require it run as root. On a single-user installation, it could be anything.
EDIT: Ah, didn’t notice you were on nixos. That makes it VERY strange, unless you turned off nix.readOnlyStore

By default NixOS does remount the /nix/store as a read only bind-mount, unless you deactivated nix.readOnlyStore
If though you indeed deactived it, any process owned by root could essentially have done that.

No, nix.readOnlyStore is active (and I never deactivated it … to my knowledge)

Is it possible that something weird happens with shutdown order? Like the access times are all when I shutdown my computer, so maybe /nix/store get unmounted as read only before the waydroid-container service begins its shutdown?

I’m not the foremost expert on this, but I believe nix will temporarily remount the directory read-write when it’s writing to the store, right? If the waydroid command is invoked by root in that window, surely python will start creating cache fles in the store?

It’s not time-based, it’s process based. The nix daemon always has rw access, and other processes are always ro.

Shutdown and boot are indeed the only 2 occasions when I can see such a race happen.
I have not enough insights into how exactly the boot process works, or how systemd determines shutdown order, though before the remount and after RO gets released, to be able to actually “release” /, there is a chance for other processes to write the store.

Looking through my system logs on the 1st of July and commit history, I was reminded of something weird that happened.
I had encountered this issue glibc locales cause nixos-rebuild to fail · Issue #179486 · NixOS/nixpkgs · GitHub then upon adding the requested locales, I accidentally ran sudo nixos-rebuild switch instead of dry-activate. This triggered a lot of services to be reloaded and eventually failed. The time of this event aligns with when the directory was created.

Ok so I think this is due to the Gnome bug
find /nix/store -perm -600 -a -not -type l -print \
| (xargs nix path-info 2> /dev/null) \

This stats the registered store paths that contain writable files. There are a lot of unregistered paths in there that are ultimately red herrings. On my system, I just get two packages this way:

I’m noticing that they were both “Changed” on May 12th, which is exactly the day I reinstalled this system and configured it for Gnome the first time. I managed to “fix” the Gnome bug on my system by manually disabling PackageKit on June 16th. The Access time on those paths is not after that date.
So I’m thinking the fact that PackageKit remounted my /nix/store writable allowed something to mess with these paths.
