How to stop TRAMP from asking for sudo password on every startup?

How to stop TRAMP from asking for sudo password on every startup?

[Jonathan Groll]

Is there a customisation option to stop TRAMP from asking for the sudo
password upon launching emacs? Sometimes I don't want to do any sudo
edits, but it still asks every time. This problem seems to have
started after I opened some buffers with /sudo::/ , from what I can
tell there is nothing in my .emacs or custom.el actively starting
tramp.

Many thanks,
Jonathan.

Are you using session.el or desktop.el that some buffers are restored  
when GNU Emacs is launched?

Could you also report versions of GNU Emacs and of TRAMP, please!  
(variables emacs-version and tramp-version)

The only time I get asked for the password at startup is if I closed
Emacs with desktop-save-mode set to t, and a "/su::" file open.  I make
sure to kill those buffers as soon as I'm done with them and then no
problems!

If, on the other hand, you still get this behavior then please file a
bug report.

Tramp 2.1 has a function to remove all remote buffers. The following
might help you (untested):

  (add-hook 'desktop-save-hook 'tramp-cleanup-all-buffers)

Yes, please.

Sweet!  That will save me thirty seconds at the end of every day ;)

Do you use desktop.el or some other package that saves state between
sessions?

Aha! You've set me on the right track, it was:
(require 'recentf)
(recentf-mode 1)

Many thanks,
Jonathan.

See variable `recentf-keep'. The following might prevent the trouble in
the future (I assume you're running Emacs 22):

  (add-to-list 'recentf-keep 'file-remote-p)

With Emacs 23, this won't be necessary.
