libpam-systemd 204-5ubuntu20.19 (arm64 binary) in ubuntu trusty

 systemd is a replacement for sysvinit. It is dependency-based and
 able to read the LSB init script headers in addition to parsing rcN.d
 links as hints.
 .
 It also provides process supervision using cgroups and the ability to
 not only depend on other init script being started, but also
 availability of a given mount point or dbus service.
 .
 This package contains the PAM module which registers user sessions in
 the systemd control group hierarchy
