Re: Vendor import push failed: src refspec ... does not match any

Thanks for the responses.  Some followup:

Does the documentation at:

https://docs.freebsd.org/en/articles/committers-guide/#vendor-import-git

Need to be updated?

Specifically, section 5.4 never talks about including a '-b' flag in the
git worktree command. '-b' is mentioned for creating a new vendor branch
but sendmail as a vendor is not new and the branch is already listed as
existing:

https://cgit.freebsd.org/src/log/?h=vendor/sendmail

I'll note this is not the first vendor import of sendmail source so I
want to make sure not to break anything by creating a new branch for a
pre-existing vendor package.

Happy to restart once I am sure I won't break the existing vendor import
of sendmail.
