I've recently noticed Eshell is now calling tramp for every sudo
command. Tramp is very slow, and I believe for most cases tramp
intermediation is unnecessary.
Could we please add a customizable switch to enable/disable
eshell/sudo? Disabling eshell/sudo by default would be even better.

All built-in commands of eshell can be disabled by prepending "*". See
(info "(eshell)Built-ins")
That means, you shall call
~ $ *sudo command
Best regards, Michael.

Yes, I am aware of that. Thank you. And I'm also aware
I can just remove eshell-unix from eshell-modules-list.
Inside em-unix.el are
eshell/agrep
eshell/cat
eshell/cp
eshell/diff
eshell/du
eshell/egrep
eshell/fgrep
eshell/glimpse
eshell/grep
eshell/info
eshell/ln
eshell/locate
eshell/make
eshell/man
eshell/mkdir
eshell/mv
eshell/occur
eshell/rm
eshell/rmdir
eshell/su
eshell/sudo
eshell/time
eshell/whoami
Some are beneficial, but many command wrappers are not -- at
least to me.
I think it's a good idea to give the users freedom
of choosing which eshell commands to opt-in or out.

(eval-after-load "em-unix"
(progn
(unintern "eshell/su")
(unintern "eshell/sudo")))

FWIW, I think `unintern' is a bit drastic. `makfunbound' would be my
preferred choice.

Thanks. Just another function I didn't know.

fmakunbound does the job, yes. But i just think providing a defcustom interface

is better rather than manual enable/disable through a raw function call.
I'm speaking from user's perspective, not elisp programmer's. It's
just me though.

I don't know, whether another defcustom is needed. Eshell gives you
already configuration hooks, for example:
(add-hook 'eshell-named-command-hook
(lambda (command args)
(if (member command '("su" "sudo"))
(throw 'eshell-replace-command
(eshell-parse-command (concat "*" command) args)))))
Alternatively, one could disable the alias commands interactively in
eshell, without further configuration:
~ $ fmakunbound (quote eshell/su)
~ $ fmakunbound (quote eshell/sudo)
I will document both approches in eshell.texi.

OTOH adding an alias to su/sudo can solve problem:
alias sudo *sudo -p Password: $*
alias su LC_ALL=C *su -l
(if you enter the alias from eshell, you have to escape $)

Excellent. Aliases stay persistent, so it is the complete solution. I've
added this to eshell.texi.
Best regards, Michael.

I'm not sure either. But fmakunbound is clearly not good enough since
it can't easily be undone.
> alias sudo *sudo -p Password: $*
> alias su LC_ALL=C *su -l
That's a better solution, yes.
