Using the Image Builder to Modify the Software Image
When you use the Image Builder, it creates a builder directory. On a PC, the
directory is \wf\builder.dir. On a UNIX workstation, the directory is
defined by the environment variable BUILDER_DIR. You should have already
defined this variable during the Quick-Start procedure (refer to Quick-Starting
Routers for instructions).
This directory may contain portions of old images that are no longer in use, unless
this is a new installation. You can remove these partial images to free up space on
your PC or UNIX workstation.
Be sure you have enough space on the destination router volume to transfer the
new or modified image to the router. To check the available space, refer to
Chapter 5 for instructions.
Removing Software Components
You can remove files from the software image to make more space available on
the router software volume.
The Image Builder will not let you remove essential files. This protects the most
important files that make up your router software image. For example, you cannot
remove the Operating System Kernel file from the baseline router software
component. Also, because the baseline router software component contains
essential files, you cannot remove it from the list of current components.
To remove components from the software image:
1. In the main Site Manager window, choose Tools > Image Builder.
The Image Builder window opens (refer to Figure
6-1).
2. Load the router software into the Image Builder.
Refer to “Loading Image Files into the Image Builder
” on page 6-7.
3. Select the file in the Current Components list that you want to remove.
The Remove button appears in the Image Builder window (Figure
6-4).
If you select an essential file that you should not remove, for example, the
Operating System Kernel file from the baseline router software component,
you will not see the Remove button.
