Hello,

Please keep the Buildroot mailing list in Cc. Thanks!

Using branch names as versions for Git-fetched packages was never
supported. Because:

 (1) It breaks the principle of reproducibility: the state of the
     source code you will build depends on when you do the build.

 (2) It doesn't do what you expect, because Buildroot will cache in
     DL_DIR a tarball named <package>-master.tar.gz, and will never
     re-fetch from the Git repository. To force it to refetch, you have
     to manually remove this cached tarball.

See also the thread at
http://lists.busybox.net/pipermail/buildroot/2018-June/222961.html,
where we have been discussing exactly this topic a few days ago.

I still think there are some useful use cases for this, and that we
should support it somehow, but it's not clear how it should be done yet.

Best regards,

Thomas
