I have never seen this technique before. But being curious I tried it too
and
am getting:
su: must be run from a terminal
Are there different implementations of su out there? I have an LFS 5.1.1
There is an su command in Coreutils and in Shadow. The one from coreutils
sucks.
Ever since I can remember LFS suppresses the coreutils one and installs the
shadow
one, but maybe the suppression technique has changed. Also, LFS 5.1.1 is
probably
from the time before the merge of sh-utils and textutils into coreutils, so
you
should best go back and look at the relevant chapters of the 5.1.1 book in
the LFS
museum. If you skipped the supression command you might have ended up with
the wrong version.
Running 'su --version' might help you to indentify your binary. Recent
coreutils
versions will respect that switch and clearly print out that it is from
coreutils.
Recent shadow versions will complain that it's an unrecognized option and
print
a usage message. I also have an older su binary lurking on my box (probably
from the shadow version used in LFS 4.0) which treats the --version arg as
the user name to su to, and will prompt for a password.
