Re: Emacs tramp troubles with old Sun

["Robert J. Chassell" <bob@rattlesnake.com>]

Today's GNU Emacs CVS snapshot, Wed, 2007 Nov  7  20:59 UTC
GNU Emacs 23.0.50.2 (i686-pc-linux-gnu, GTK+ Version 2.12.1)
started with

     /usr/local/src/emacs/src/emacs -Q -D


I can reach fp.gnu.org, but the old Sun still fails with

    Couldn't find exit status of `test -e /tmp'


I can reach it  with    ssh -l bob shell.berkshire.net
