+Subject: [PATCH] determineVersion.sh: prevent traversing into outer git repo
+ for git-describe call
+
+When building nethogs inside another git repo (as is i.e. done as part
+of a buildroot build) the version is picked up from the outer git repo,
+which is confusing as well as introducing reproducibility problems when
+rebuilding the same nethogs version produces different results if the
+outer repository changes.
