2.12. firstboot

The firstboot utility runs after installation. It guides the user through a series of steps that allows for easier configuration of the machine.

The following known issue applies to the IBM System z architecture:

When firstboot is running in text mode, the user can only register to Red Hat Netwrork legacy, not with subscription-manager. When firstboot is running in GUI mode, both options are available.
The IBM System z does not provide a traditional Unix-style physical console. As such, Red Hat Enterprise Linux 5 for the IBM System z does not support the firstboot functionality during initial program load.
To properly initialize setup for Red Hat Enterprise Linux 5 on the IBM System z, run the following commands after installation:
- /usr/bin/setup — provided by the setuptool package.
- /usr/bin/rhn_register — provided by the rhn-setup package.
