I just wanted to let everyone know so no extra time is wasted..
If you are working with the installer then IPA gets installed which starts nscd.
nscd attempts to cache various things including user and group lookups which
BREAKS BUILDING IMAGES (they can't unmount cleanly). This includes building
the node-image. So, this is just a reminder to turn off nscd if it's
running on your build box. :)

So, this is just a reminder to turn off nscd if it's running on your build box. :)I think newer versions of livecd-tools fixes this by turning off nscd before building the livecd image and then turning it back on when the creation is done. See the following BZ: https://bugzilla.redhat.com/show_bug.cgi?id=481796 The bz isn't clear on which version of livecd-tools does the nscd stop/start hack. Perry

The hack of turning off nscd from livecd-creator itself wasn't working, so I didn't push it to git :/ Unfortunately anything like that really is just a hack -- the only "right" thing to do is fixing nscd and prospects for that seemed grim :( Jeremy [1] Which is off right now due to the power outage in Westford or I'd post it for others to try out :)
