Upgrading System Software
This chapter outlines procedures for upgrading software to a new release level.
7.1. !Jtep 1: What To Save
No matter what version of the system you may be running, you will have to rebuild your root
and
lUI'
file systems. The easiest way to do this is to save the important files on your existing
system, perform a bootstrap as if you were installing a software release on a brand new
machine, then merge the saved files into the new system. The following lists the standard set of
files you will want to save (in addition to all user flies) and indicates directories in which
site-specific files should be present. This list will probably be augmented with non-standard files
you have a.dded to your system; be sure to do a tar of the directories
/etc/, /libl,
and
/uI,/lib/
so that you don't miss anything the first time around.
