I'm failing at my first attempt at creating (or recreating) a live CD

- I'm using Fedora 8 (because I don't find KDE in F9 usable yet)
- I have SELinux disabled.

Following the process described in the LiveCDHowTo, well, actually
the step:

livecd-creator --config=/usr/share/livecd-tools/livecd-fedora-minimal.ks

resulted in a complaint about SELinux not being enabled on the host system...
Right, so I edited the '.ks' file and set selinux=--disabled

This let it proceed through the build stage with the following errors:



  Installing: info                         ##################### [ 29/129]

Then I used the specified command to execute the ISO image:

qemu -m 512 -cdrom livecd-fulko-200805241043.iso

The first time I followed the procedure (a few days ago) to
build the ISO and execute it, it wouldn't even boot.
Today I retried the same procedure, and today it boots,
but after it get to the point of starting udev, something
flashes by on the screen (qemu window) and then the window
goes black, and I can't see anything after that.  I seems hung.

So then I tried recreating the 'livecd-fedora-desktop.ks'
version as per instructions and it dies with:

 Installing: tzdata                       ################### [  21/1019]

    errors = self.ts.run(cb.callback, '')

    fd = os.open(rpmloc, os.O_RDONLY)

So I'm at a loss as to how to proceed to start testing this process
even before I add my own customizations.

Any help would be appreciated.

TIA
