Gentoo Security Handbook §7.a [1] contains the following text: > Check the PAM documentation for more options. In the quoted text, the word “PAM” is a hyperlink to <http://www.kernel.org/pub/linux/libs/pam/Linux-PAM-html/sag-pam_cracklib.html>, which does not appear to exist (my attempts to dereference the hyperlink yield 404 Not Found responses). [1]: <https://www.gentoo.org/doc/en/security/security-handbook.xml?part=1&chap=7#doc_chap1>
Done, thanks! New location is at http://www.linux-pam.org/Linux-PAM-html/sag-pam_cracklib.html
