On F16 I tried building the Fedora Scientific KDE spin and it worked perfectly.
The ISO is 2.4GB.
So, it looks like you'll not have any problems with fsck if you stick to only adding/removing official Fedora RPMs.
But if you add your own (non-RPM) files in the POST section you'll run into problems.

Hi James

I tried once more and rebooted after disabling sandbox and cups.
Still failed after the resize on the fsck.
I can make small remixes - 1.4GB and smaller,, but nothing larger.

I wonder how the folks who made Fedora Scientific Spin (2.4GB Live F16 DVD) did it?
Is it because they use KDE and not GNOME?

Hi John,

the last thing which comes to my mind is that you make sure to make a 
reboot after disabling the services. After the reboot it worked on my 
system (RHEL 6.2) without any flaws.
