I am trying to manage my gnome keyrings with git annex (see this article if curious - my variation uses git annex for binary files).
But I see ~/.local/share/keyrings/Default_keyring.keyring is changing from time to time, even if I don't add or remove any key.
What is writing to it? could it be the act of logging in? Or just unlock the screen?
How can I prevent this?
I still would like to back it up since some of the keys there are important, but I don't want to be misguided by git status stating that the file has changed even if nothing relevant has been changed.
I noticed a file (~/.local/share/keyrings/default) with the content "Default_keyring" wich, I presume, points to the default keyring (!). But what is it the default for? Could I change it to point to an untracked keyring, like "Trash_keyring"?
Or how could I move those important keys to some other keyring?

Why won't you disable the keyring altogether if you're not using it? Why does this bother you, is it significantly growing in size?

I do use it.
Like I said, some of the keys are important.
It bothers me because I would like git annex to notify me only if I add/remove keys from it, not every single day, multiple times a day even.
