firewall directives not working for livecd-creator
by Tim Coote
Hullo
I'm trying to create a spin using livecd-creator from livecd-tools-15.7-1.fc15.i686. However, I cannot get any firewall rules to pass through from the kickstart to the the livecd. I always seem to get a default firewall config that blocks everything, and the rules that I wanted in /etc/sysconfig/iptables get mv'd to /etc/sysconfig/iptables.old.
Elsewhere I've seen comments to this effect, but cannot find the definitive position in a bug tracker. Am I correct and how can I work around this?

Expanding the overlay size
by Phil Meyer
The livd images currently appear to have 4GB filesystems, which would
correspond to single layer DVDs. This is ok.
My question: Is the entire free space reported by tools like 'df'
supposed to be writable?
My simple tests indicate that it is not.
ie:
# df -h .
Filesystem Size Used Avail Use% Mounted on
/dev/loop6 4.0G 1.3G 2.7G 33% /
# wget

So it seems that roughly 500MB is available via an overlay.
Only 'livecd-iso-to-disk', of all of the livecd tools, has an overlay
option.
The question is:
How to adjust the overlay somewhere during the process of:
livecd-creator -> livecd-iso-to-pxeboot
such that a system using the initrd.img created by
'livecd-iso-to-pxeboot' has all of the remainder of the 4GB file-system
available via the overlay.
Thanks for any pointers!
