[Fedora-spins] problems creating official spins locally

[John Poelstra]

At last week's meeting I volunteered to create a simple wiki page to 
help anyone build one of the official spins and also build some of the 
spins for testing.

I ran into several problems doing this last week.  Some were 
self-inflicted (running out of disk space in the root partition), but 
others were more mysterious.  Like kicking off the livecd-creator, 
watching it download all the needed packages and start to yum install 
them, only to watch it hang on several occasions after installing 400 or 
500 packages.

1) Is building live CDs on Fedora 10 for Fedora 11 a bad idea?

2) Where can I collect troubleshooting information on why the yum 
install process hangs?  Nothing obvious in /var/log/messages

3) What is the best way to cleanly abort a failed/hung live CD creation? 
  I ended up having to reboot my system to unmount the loop devices and 
clean up all the space taking in /var/tmp because killing the process or 
trying to force unmount the loop device didn't work.

Thanks,
John
