bug#5300: su command does not elevate user privilege to root when run inside term/ansi-term mode

[Praveen A]

Hi,

su command does not a make a normal user root when run inside term
mode. A full terminal emulator is expected to work with su.

Thanks
Praveen

So what does happen then?

emacs -Q -f term
bash RET
bash> su
password RET

works fine for me. So does ssh.

It just gives you the normal user shell prompt (both for ssh and su)

pravi@savannah:~$ ssh localhost
pravi@localhost's password:

I'm using emacs 23.1+1-5 from debian testing, it is also failing with
a trunk built emacs too.

So, it seems to work fine, but when the shell finishes initializing it
logs out? Is there anything odd going on in your shell configuration
files (bashrc, profile, etc?)

All the configurations are default ones. Moreover both su and ssh are
working with gnome-terminal. I tried these commands in trunk compiled
emacs and packaged emacs both on fedora 12 and debian squeeze/testing,
it is failing every where.

I will try if the same problem is there on my colleagues' systems tomorrow.
