the meaning or effect of this script. But I think that you need to use
the "runcmd" option. For example:
<action>
...
<initialization>
<cloud-init>...</cloud-init>
<custom-script><![CDATA[runcmd:
- touch /iwashere
]]></custom-script>
</initialization>
</action>
If you use this it should run the "touch /iwashere" command, and you can
check that it did verifying that the "/iwashere" file exists.
As I said I didn't test this, so I may not work. I'd appreciate if you
can test it, and once it works update the wiki with the correct
instructions:
