I just rebuilt the latest emacs master, and found that I can no longer use
sudo in eshell.
I get the error message:
Don’t know how to make a buffer-local variable an alias:
tramp-use-connection-share

This variable was recently introduced:
https://github.com/emacs-mirror/emacs/commit/1c39347d58533280bae74c712ad0016a5c8992aa

To expand on my earlier report, I am using the `eshell-tramp` module.

I tried to reproduce, but I cannot. Both versions of sudo in eshell work for me:

Could you pls provide a recipe, starting with "emacs -Q"?

Best regards, Michael.

I'm not able to reproduce this either, but here's what I tried from 
"emacs -Q":

   M-: (require 'eshell)
   M-: (add-to-list 'eshell-modules-list 'eshell-tramp)
   M-x eshell

   ~ $ which sudo
   eshell/sudo is a byte-compiled Lisp function in ‘em-tramp.el’.
   ~ $ sudo *whoami
   root

Chris, you could try running "make bootstrap", or at least "rm 
lisp/eshell/*.elc && make" to make sure that the Eshell code gets 
recompiled. Eshell makes pretty heavy use of defmacro and defsubst, so 
sometimes the bytecode files end up out of date and you need to get rid 
of them.

Bug#62329 is the same problem, I'll use the recipe from there. Merging
both bugs.

Best regards, Michael.

My previous attempt to merge this bug with its original version used a 
totally-wrong bug number for the dupe due to me mis-pasting the command. 
Hopefully this works...

Well, I know marking as done works; sorry for the noise.
