Thanks very much for the explanation. I couldn’t figure out if it
would be an issue with direct async.

This is a solution for me, thank you. Please do close the ticket.

I would like the documentation to be a little clearer about the fact
that the remote default shell is used in many methods (and not
/bin/sh). I will explore filing a patch for that.

Thank you for your help and for maintaining the very useful tramp!

best, Erik
