How to persist usroverlay changes?

I'm doing something really simple: changing the plymouth theme to a custom one on Bazzite Gnome desktop.
Ideally, this should not involve me needing to copy the theme into

/use/share/plymouth/themes

/use/share/plymouth/themes

/use/share/plymouth/themes

/use/share/plymouth/themes but apparently that's where it wants to look for it.

I managed to copy it over with

rpm-ostree usroverlay

rpm-ostree usroverlay

rpm-ostree usroverlay

rpm-ostree usroverlay and apply it, but, to no one's surprise, changes done by usroverlay are transient and disappear on the next reboot. Is there a way to make these changes persist, but still keep them layered so they're not affected by updates?

Thanks!

--hotfix--hotfix will keep them until you update

and if you want it permanent even for updates, then you need to make a custom image that just takes our image, slaps the files into that folder and makes a new image from that and pushes that to you

That.. sounds way more involved than what I'm hoping to do for this use case...

Thanks for the responses though, I guess I'll live with it. I wish there was an easier way to overlay files just like we can layer packages, without spinning up an entire image.
