PAM

To use PAM, the pam package itself must be installed as well as something for logging into the system that supports PAM. The login bundled with busybox does not support PAM. Instead, one of the following may be used:

• greetd plus any greeter (agretty looks like login). See (greetd's website for more information).
• login(1) provided by shadow-login
• login(1) provided by util-linux-login
