Question: gitflow.branch.feature/{feature}={base} and git flow feature track {feature}

[k-pd]

When starting a feature branch using

git flow feature start {feature} {base}

there is an entry in git config -l for it:

gitflow.branch.feature/{feature}.base={base}

Publishing and tracking is working well, as long as {base} is the default branch used in both repositories.

But how about a different {base} or different default branches? Will git-flow know the original {base} from git history?

When tracking the remote feature

git flow feature track {feature}

there is no entry in git config -l to know the remote branches {base}.

Where to even know the original {base} from?

Edit: .base was missing from config key
