Hi Scott,
I wipe and reformat with ext3.
And it does sound like someone put an artificial 3 GB
barrier into it to accommodate max single file size
limitation of FAT.
With the following on a 16 GB ext3 stick:
livecd-iso-to-disk --overlay-size-mb 13287
Fedora-Live-Xfce-x86_64-21-5.iso /dev/sdc1
It will tell you the max "--overlay-size-mb" is 13287 if
you tell it something larger than it likes.
But, even when adjusted to make the stinker happy, you
still get 3 GB.
So, basically, is this a bug? And, has it been fixed
anywhere?

It is important to understand that Fedora LiveCD technology is based on
embedded filesystems,
an ext4 filesystem and partition (inside the ext3fs.img file) that is
compressed inside a SquashFS
filesystem (inside the squashfs.img file) all saved on the LiveCD or .iso
file in an ISO 9660 filesystem,
or on a LiveUSB device in the LiveOS folder of the device filesystem (which
may be a fat, extX, or
other filesystem). With this technology, when one sees or thinks about a
file or filesystem size, one
must be careful and clear about which of the many simultaneously present
filesystems one is
referring to.
