installation diskette. If it exists, this file will be executed at the end of
the installation process before the system reboots. This can be used, for
instance, to execute the sample script
/usr/lpp/sysback/scripts/install.post_rmnet that removes the network
configuration from the restored system data to prevent any prompts at
the end of the SysBack installation process.
LVM Information File
Enter a filename to include an LVM information file on the customized
installation diskette. Doing so replaces the LVM information contained
on the backup and is typically used to apply many changes to the LVM
information without requiring the user to do so using the installation
menus. For more information about how to create a customized LVM
information file, please refer to “Creating or Editing an LVM
Information File” on page 16-18.
Changing the Read Permission on a Disk Image File
When you back up to a disk image file, you can set the read permission of the file
to allow only the original host and/or original user to read from the file. You
might need to change this permission at a later time if, for instance, you need to
use an image file with “original host only” permission as a network installation
image for other systems.
Using the Change Read Permission on a Disk Image File option, you can change
the owner of the file (host and/or user), the backup description, if any, or the host
or user read permission.
Only the following users have permission to change the read permission of a disk
image file:
v Root user on the system where the file physically resides
v Root user on the system from which the file originated
v User on the system who originally wrote the file

1. From the Utilities menu, select Change Read Permission on a Disk Image File.

from this list and change it on the Change Read Permission on a Disk Image
File screen that follows.
