Now, I'm not sure whether this need to be backported at all. Isn't it the file in main that is triggered by addition of a tag?

Extracting the tarball

Just for clarification: where (in the CI?) is the tarball created? Because the release tarballs contain the version in the directory name.

The tarball is created in CI and added to the Assets section of a release (e.g. https://github.com/OSGeo/grass/releases/tag/8.4.0). That tarball is/was named correctly, e.g. grass-8.4.0.tar.gz, but the same tarball extracted a containing directory named only grass (because of the git repo name is "grass"). With this change the container directory will be named grass-8.4.0.

This/these tarballs may (or rather should, as include/VERSION_GIT file is generated into it) be uploaded to the osgeo download server manually (in the future possibly automatically).

Oh, I had completely forgotten about this one... and it would affect the upcoming GRASS GIS 8.4.1.

I didn't :-), and yes, that's why I hurried up with this now.

I cannot really judge the code but full trust.

To test this locally, try:

# Assuming grass repo directory name is 'grass'
cd to_grass_repo
cd ..

GRASS_V=grass-8.4.2

# before
tar -cvf ${GRASS_V}.tar --exclude=".gi*" --exclude=".tr*" --show-transformed-names grass

# with this change
tar -cvf ${GRASS_V}.tar --exclude=".gi*" --exclude=".tr*" --transform s/grass/${GRASS_V}/ --show-transformed-names grass

With the --show-transformed-names option the tar command only prints out the outcome instead of creating the tar archive too. (I added it here for testing purposes only).

Backported to 8.4 with eb9cd95.
