Getting ready to build LFS-7.5 and want to "head off" some situations before I begin. Somewhere in my last {,B}LFS build, I lost--or never had--the ability to run "su" or "su -" Yes, I have sudo, but I use the Package Users--I know, I know--System and need "su." I have PAM installed currently and used Christopher Gregory's solution, documented on a recent post to "blfs-dev" and copied /etc/pam.d/su to /etc/pam.d/su-1. This did not solve the situation.

Here is the result of running

-rwxr-xr-x  1 shadow-4.1.5.1 shadow-4.1.5.1    135159 Dec 11  2013 su

Does "su" need to be owned by root or run suid to work? Do the files in /etc/pam.d need to be owned by root?

I know that PAM is a BLFS thing and I've never used it before my last build. Needed it to satisfy dependencies for BLFS packages that I wanted to use.

Thanks,
Dan
