<mark_weaver>and then, when you hit eject, it might have tried to write some updates to the old filesystem or something.
<mark_weaver>that's one thing I've noticed with gnome 3: if you want to write an image over an existing removable filesystem, you have to manually run the umount command; if you eject using the GUI, it will not only umount, but also make the entire device go away.
<gry>abaw: Hi. https://gnu.org/software/guix/manual/guix.html says "Guix is compatible with Nix, so it is possible to share the same store between both." but someone should confirm whether this works the way you intend (I think it would, but I'm only starting to read the docs and did not even try it out yet)
