How to upgrade from 1.7.4 (or 1.7.5) to 2.0.0. Note: Things you have to do as root are marked with a # sign. The ! sign marks the actions of bin. # Replace the sources, that's /usr/include, /usr/man, and /usr/src, with the 2.0.0 sources by extracting the SYS.nn images in the normal way. (Don't forget to move or remove the 1.7.4 stuff.) ! Move to /usr/src/lib and type 'make install'. You need new libraries for the new kernel. ! Customize /usr/include/minix/config.h to add or remove drivers. In /usr/src/tools type 'make hdboot'. Reboot. ! Your system should now be running 2.0.0. Install the commands from CMD.nn and use 'make install' in /usr/src to recompile the rest of the system. # Run 'checkhier' to check your top level directory tree. It suggest commands to execute to fix descrepancies in the top level directory tree. # Compare all files in /usr/src/etc with those in /etc. Some may have changed and should be replaced. Be careful not to lose changes you have made to files in /etc.
