Description
This workaround can be dropped :)
The original issue report workaround we presently use, and the verified alternative workaround (via buildx arg) are no longer appear required since upstream commits (1 + 2) in late 2021 have patched the logic in the Debian Postfix package post-install script 🎉
Original PR
UPDATE: The first commit of this PR was prior to checking the status of the Debian package, so a follow-up commit removes those changes as they're no longer needed 😎
@casperklein spotted an issue with the original workaround that the initial commit of this PR resolves, although it never caused a problem as without a shebang the existing shell itself was used (I've verified).
