Description of problem: The /etc/pam.d/su-l and /etc/pam.d/runuser-l files appear to be completely undocumented. The files themselves have no comments. The /usr/share/doc/coreutils-6.9 files don't mention them. The man pages don't mention them. The info pages say "this command has PAM support" but then point the user at the plain 'su' and 'runuser' files, ignoring the *-l variants. Version-Release number of selected component (if applicable): 6.9-3.fc7 Steps to Reproduce: 1. See "su-l" mentioned in logwatch report. 2. Fail to find explanation anywhere in docs, --help, FAQs, bug lists. 3. Become mildly annoyed at the presence of undocumented /etc files. 4. Become slightly alarmed at "su-l" appearing in strings(1) output on /bin/su with no explanation. Actual results: I had to look at coreutils-split-pam.patch in the srpm to confirm my guess that these files had something to do with the -l option. Expected results: I would have expected the parts of the docs that mention PAM support in the first place to include "If the -l option is given, the corresponding *-l PAM file will be used instead. By default, these include the base PAM file and then add some additional blahblahblah..."
Added a bit words about those runuser-l and su-l files with different PAM file to man pages of coreutils-6.10-1.fc9 (now built in RAWHIDE).
