Oh indeed. I think that=E2=80=99s because / is already an overlayfs in =E2= =80=98guix system vm=E2=80=99, so somehow we can=E2=80=99t just stack another overlayf= s there. I should test in a standalone image produced by =E2=80=98guix system vm-ima= ge=E2=80=99 instead. Sorry for the confusion! Ludo=E2=80=99.
