What problem are you trying to solve?

All the files on a newly installed system are created by the
installation process. Many of them are on the installation DVD and are
simply copied. Some are created and populated during the installation
process using data supplied by the person doing the installation.

Note that CDs are NOT available for S10; you can download images of the
CDs and burn your own. Solaris is distributed either on DVD or by
downloading the files that would be supplied on the DVD. The DVD used
to be supplied at nominal cost and may still be. Have a look at Sun's
web site and see if you can find it. If you are burning your own
CDs/DVDs remember that you are burning IMAGES. A common mistake is to
burn the image *as a file*. If you do that you wind up with a file
system consisting of a director and a single file. It will not boot.
The image IS the whole damn thing and if you burn the image you will get
a root directory and a number of files.

You should be able to retrieve template files from the DVD. (If you can
find them!)

You may find that some files are created and populated by the
installation process rather than simply being copied.

Just 'cp' it back:

# ls -l /.zfs/snapshot/install/etc/inet/hosts
-r--r--r-- 1 root sys 1049 Mar 20 2009 /.zfs/snapshot/install/etc/inet/hosts
# cp /.zfs/snapshot/install/etc/inet/hosts /etc/inet

ZFS snapshots are nice.

Because of zones, Solaris 10 squirrels away a pristine
copy of volatile/editable files:

First find the package it belons to:

# pkgchk -l -p /etc/hosts
Pathname: /etc/hosts
Type: symbolic link
Source of link: ./inet/hosts
Referenced by the following packages:
SUNWcsr
Current status: installed

# pkgchk -l -p /etc/inet/hosts
Pathname: /etc/inet/hosts
Type: editted file
Expected mode: 0644
Expected owner: root
Expected group: sys
Referenced by the following packages:
SUNWcsr
Current status: installed


Then you can find the file under the save/pspool
directory:

/var/sadm/pkg/SUNWcsr/save/pspool/SUNWcsr/reloc/etc/inet/hosts
