3.8 Unattended Installations
Building Drivers and RPMs for Unattended Installation
Linux unattended installation requires building two drivers:
• A minimal installation Solarflare driver that only provides networking support.
This driver is used for network access during the installation process.
• An RPM that includes full driver support. This RPM is used to install drivers in
the resultant Linux installation.
Figure 8: Unattended Installation RPM
Figure 8 shows how the unattended installation process works.
1 Build a minimal Solarflare driver needed for use in the installation kernel
(Kernel A in the diagram above). This is achieved by defining “sfc_minimal” to
rpmbuild. This macro disables hardware monitoring, MTD support (used for
access to the adapters flash), I2C and
debugfs
. This results in a driver with no
dependencies on other modules and allows networking support from the
driver during installation.
