Use the installadm delete-manifest command to remove the specified AI manifest or derived manifest script from the specified install service. The manifest name is the same name that the installadm list command returns, as shown in Example 8–38.
You cannot delete the default AI manifest.
The following command removes the sparc-ent AI manifest from the solaris11_2-sparc install service:
# installadm delete-manifest -m sparc-ent -n solaris11_2-sparc
