The file you seek is in quite a few places, including in tarballs (of
sorts) on the installation CD-ROM. However, it's not surprising you didn't
find it: The gzipped tarballs are there, but they've been split into
subfiles.
There are several ways to get the file you mentioned, /etc/rc.conf:
1. Get it from the "source" distribution tarball. Mount the installation
CD-ROM. `cd' to its "bin" subdirectory, and run the following command.
That command will put the gzipped tarball back together again,
uncompress it, and extract "etc/rc.conf" onto standard output, which is
then redirected to "/tmp/rc.conf". Note the lack of leading "/" in
"etc/rc.conf".
cat setc.?? | tar xzfO - etc/rc.conf >/tmp/rc.conf
2. Get it from the "bin" distribution tarball. Mount the installation
CD-ROM. `cd' to its "bin" subdirectory, and run the following command.
cat bin.?? | tar xzfO - etc/rc.conf >/tmp/rc.conf
This will take longer than #1, since the "bin" tarball is enormous.
3. Get it from the source CD-ROM. This time, you don't need to worry about
a tarball at all; "/etc/rc.conf" exists as a separate file on the live
file system. Put the "live file system" CD-ROM in your drive and mount
it. You'll find "rc.conf" in the "etc" subdirectory on that disk.
4. It's also in the CVS repository disk, if you have Walnut Creek's
2.2.5-RELEASE CD-ROM set.
