8.1 SunOS 4.1.X

8.1.2 Overview of Sysgen process

: 1. cd /usr/share/sys/sun[3,3x,4,4c,4m]/conf
: cp GENERIC HOSTNAME - copy the configuration file
: vi HOSTNAME - edit and revise as needed
: config HOSTNAME - build the system configuration files
: cd ../HOSTNAME - cd to the new directory
: make - compile the new kernel
: mv /vmunix /vmunix.gen - save the old kernel
: cp vmunix / - install the new kernel
: reboot - reboot using the new kernel

Sometimes the new kernel will not run properly. The patch may have been faulty; you may have left out defining one of the necessary parameters; the object files may have been corrupted, etc. If you can't boot from the new kernel for any reason, reboot using the old kernel and then repeat the steps above to regenerate a new kernel. Reboot with:

>b vmunix.gen
