After upgrading sys-libs/pam from 1.3.1_p20200128-r1 to 1.4.0_p20200829, pam.conf(5) manual page disappeared: $ qlist -Iv sys-libs/pam sys-libs/pam-1.3.1_p20200128-r1 $ man -aw pam.conf /usr/share/man/man5/pam.conf.5.bz2 $ qlist -IUv sys-libs/pam sys-libs/pam-1.4.0_p20200829 -abi_mips_n32 -abi_mips_n64 -abi_mips_o32 -abi_s390_32 -abi_s390_64 -abi_x86_32 abi_x86_64 -abi_x86_x32 -audit -berkdb -debug filecaps -nis pie -selinux split-usr $ man -aw pam.conf No manual entry for pam.conf pam-e42e178c71c11bb25740a5177eed110ee17b8af2.tar.gz contains the page in doc/man/pam.conf.5.xml. The page is probably missing from a pregenerated pam-1.4.0_p20200809-doc.tar.xz archive. (I can see that an upstream requires a web browser for converting Linux-PAM_SAG from an HTML format to a plain text format. But since Gentoo does not deliver that manual, it could make sense to patch the build script to skip targets in doc/{sag,mwg,adg} directories. A dependency on libxslt2 and docbook-xsl-stylesheets required for the manual pages should not have been an obstacle.)
It seems that documentation in doc/man directory is not built anymore, instead some external (to the upstream pam project) archive https://dev.gentoo.org/~zlogene/distfiles/${CATEGORY}/${PN}/${PN}-1.4.0_p20200809-doc.tar.xz is expanded. Not only pam.conf(5) is missing. This is a regression.
Fixed in stable.
