I did a fresh installation of Cauldron, and noticed that the system would hang while booting after the installation. It appears that no messagebus user was created, and this caused the dbus message service or systemd to hang. install.log contains this: lib64dbus-1_3-1.4.16-1.mga2.x86_64 rpm-helper-0.24.5-1.mga2.noarch /usr/share/rpm-helper/add-user: line 25: /usr/sbin/useradd: No such file or directory group messagebus does not exist - using root dbus-1.4.16-1.mga2.x86_64 so dbus correctly requires rpm-helper, which is installed before dbus is installed, but then the command /usr/sbin/useradd is not there. rpm-helper should require this.
Full install.log is in attachment #1302 [details]: https://bugs.mageia.org/attachment.cgi?id=1302 shadow-utils is installed in the same transaction, but after rpm-helper.
Fixed in rpm-helper-0.24.5-2.mga2
