Expected Behavior

I'd expect /usr/lib64/security to contain pam_tty_audit.so

Actual Behavior

$ ls /usr/lib64/security
pam_access.so     pam_deny.so  pam_faildelay.so  pam_group.so    pam_limits.so     pam_mail.so       pam_nologin.so        pam_pwhistory.so  pam_shells.so      pam_systemd.so  pam_timestamp.so  pam_wheel.so
pam_cap.so        pam_echo.so  pam_filter        pam_issue.so    pam_listfile.so   pam_mkhomedir.so  pam_oslogin_admin.so  pam_rhosts.so     pam_sss.so         pam_tally.so    pam_umask.so      pam_xauth.so
pam_cifscreds.so  pam_env.so   pam_filter.so     pam_keyinit.so  pam_localuser.so  pam_motd.so       pam_oslogin_login.so  pam_rootok.so     pam_stress.so      pam_tally2.so   pam_unix.so

It's not there.

Other Information

I've tried taking pam_tty_audit.so out of one of the other containers; /usr/bin/toolbox, but when I add it to my pam config for sshd, it just blows up; consequently breaking sshd.

Is there some known way to add this that I'm unaware of? I've spent days scouring google and trying to get a build container together to compile it, but I've had no success.

Thanks.
