I just built the cross-lfs book, and noticed that the version of su

makes it useless. The version built in coreutils is the one I'm used to.
The shadow version of "su" does support the -c option providing you an
option to pass command line arguments to 'su.'
From its man page (based on shadow-4.0.14):
Additional arguments may be provided after the username, in which case
they are supplied to the user´s login shell. In particular, an argument
of -c will cause the next argument to be treated as a command by most
command interpreters. The command will be executed by the shell
specified in /etc/passwd for the target user.
And to demonstrate it works as advertised:
[EMAIL PROTECTED]:~$ touch /root/testfile
touch: cannot touch `/root/testfile': Permission denied
[EMAIL PROTECTED]:~$ su -c "touch /root/testfile"
Password: ************
And '/root/testfile' is created after running this.
I believe "su" from the shadow package does work as expected, unless I
totally missed something, Richard?
