-This is a fork of gentoo's sys-libs/pam package. The main reasons
-for having our fork seem to be:
-
-1. We add a locked account functionality. If the account in
-   `/etc/shadow` has an exclamation mark (`!`) as a first character in
-   the password field, then the account is blocked.
-
-2. We install configuration in `/usr/lib/pam`, so the configuration in
-   `/etc` provided by administration can override the config we
-   install.
-
-3. For an unknown reason we drop `gen_usr_ldscript -a pam pam_misc
-   pamc` from the recipe.
-
-4. We make the `/sbin/unix_chkpwd` binary a suid one instead of
-   overriding giving it a CAP_DAC_OVERRIDE to avoid a dependency loop
-   between pam and libcap. The binary needs to be able to read
-   /etc/shadow, so either suid or CAP_DAC_OVERRIDE capability should
-   work. A suid binary is strictly less secure than capability
-   override, so in long-term we would prefer to avoid having this
-   hack. On the other hand - this is what we had so far.
