When building your own AI images with distro_const it is useful sometimes to add a custom script to modify the resulting image. This is easily achievable by adding a custom script to the xml manifest provided to distro_cons.
For example, to change the default password for user jack, add the following checkpoint to the xml file, just before pre-pkg-img-mode checkpoint.
<!--
Set password to user jack, should match root password
(if hash contains slashed they need to be backslashed)
-->
<checkpoint name="lock-jack-account"
desc="Lock the jack account from login"
mod_path="solaris_install/distro_const/checkpoints/custom_script"
checkpoint_class="CustomScript">
<args>/usr/bin/gsed -i -e 's/jack:.[^:]*:/jack:XXXXXX:/g'
{PKG_IMAGE_PATH}/etc/shadow
</args>
</checkpoint>
