Hi! I'm rather new to submodules, and I have a question on something I don't understand (git-2.12.3 from SLES12): I had checked out tag v0.0.1 of my submodule. When checking the status, I see: iptables> git status HEAD detached at v0.0.1 nothing to commit, working tree clean iptables> git checkout v0.0.1 HEAD is now at b23fbdc... .version: 0.0.1 iptables> git checkout v0.0.2 Previous HEAD position was b23fbdc... .version: 0.0.1 HEAD is now at 5af0df5... v0.0.2: Fix issue with "xtables lock" /iptables> git status HEAD detached at v0.0.2 nothing to commit, working tree clean iptables> git branch * (HEAD detached at v0.0.2) master git reflog says: 5af0df5 HEAD@{0}: checkout: moving from b23fbdc0e18e570a4d9ec4cb8826afc82e2e0b64 to v0.0.2 b23fbdc HEAD@{1}: checkout: moving from ec7dd70b59e039b49bb478a3134b713a2b0a279c to v0.0.1 ec7dd70 HEAD@{2}: checkout: moving from master to v0.0 Config submodule.iptables.branch is not set. Who can explain? Regards, Ulrich
