So this is in line with this option just coming into play "When the working tree is updated", as you wrote. However I just noticed that according to the doc `--merge` should abort in that case (I think?), but it does not if `--recurse-submodules` is given.

I’d phrase it more like so : If `<pathspec>` names a submodule and the restore location includes the working tree, the submodule will only be updated if this option is given, in which case it’s working tree will be restored to the commit recorded in the superproject at the tree-ish given as the restore source. This makes it clearer that `git restore -- submodule` does nothing, and one has to say `git restore --recurse-submodules -- submodule` for the submodule working tree to be updated. > Local modifications in a restored submodule are > + overwritten.

So I would instead link to `checkout`, which does unconditionally detach the submodules HEAD. > --overlay:: > --no-overlay:: > In overlay mode, the command never removes files when > -- > Patched on top of v2.25.1-377-g2d2118b814 (git version 2.25.1) >
