It's hard to reply to list with GMail. ;-(
I am summarizing what I do to make my spin game USB key, which should
be able to save files on it.
Note that because of the way overlay persistent memory works, erasing
files on the USB key, will NOT give you more space. So you are doom
to begin once again a day.
I have read http://fedoraproject.org/wiki/How_to_create_and_use_Live_USB
and I conclude that 'the only' tool
to write a game spin disk iso image on a USB key while being able to
save on it is to use
livecd-iso-to-disk that is part of the livecd-tools package that you
could install with:
su -c 'yum install livecd-tools'
This suppose you have Fedora already installed!
I found that my USB key was /dev/sdb1 by looking the output of mount:
...
/dev/sdb1 on /run/media/paul/B874-A0CD type vfat
(rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0077,codepage=437,iocharset=ascii,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)
YOU HAVE TO BE SURE YOU ARE USING YOUR USB KEY PARTITION, NOT NECESSARY
/DEV/SDB1 BECAUSE YOU COULD ERASE YOUR DISK (I SUPPOSE) BY MISTAKE.
[paul@ip216-239-66-63 ~]$ su -c "umount /dev/sdb1"
Mot de passe :
** Avoid using more than 2000 in next line, if using VFAT **
*** Also, my system is not recent enough to use EFI BIOS, so it is
easier, read doc if your compute is too recent ***

532 seconds is a bit less than 9 mins.
So about 30 mins for all I think.
I am now ready to reboot and probably use F12 to boot on the USB key.
Wish me good luck!
