Hello: This is my first post here and comes shortly after I built my first appliance with BoxGrinder - and hopefully an useful one too - an ownCloud appliance. I have detailed the steps in my blog post here. I faced a couple of issues while at it and those are ones I would like expert opinion on: (My appliance definition file is here)

1. I ran into random unmounting problems, and James Martin's post < a href="https://issues.jboss.org/browse/BGBUILD-343?focusedCommentId=12662863&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12662863">here helped me overcome it.
2. When I had a command like '/sbin/chkconfig httpd' in the 'post' section of my appliance definition, I ran into these errors:

/sbin/chkconfig httpd on

Any ideas what might be going wrong here? Many thanks in advance.
