Script to merge persistent overlay into new image
by James Heather
There's an incredibly useful-looking script on here
http://fedoraproject.org/wiki/LiveOS_image
that merges a LiveOS snapshot overlay into a new root filesystem, and
replaces it on the USB stick, so that you get all your overlay space
back. I've been looking for such a script for a while.
Is it included in livecd-tools? Or any other Fedora package? (I'm
reluctant to run the script on the web page, because I'm not sure how
well tested it is.)
The script appears to claim that it can cope with being run from the USB
stick itself, while it's booted up, which sounds too good to be true
(or, at least, too good to be safe).

shutting down f19-livecd corrups raid1
by Joshua C.
My raid1 gets corrupted _everytime_ I shut down a
f19-kde-livecd-image. I used kernel.f19 and mdadm.f19 in a f17-livecd
and everything works fine. So these two are not the problem.
What should I look at? maybe dracut???
PS: Testing and experimenting isn't a good idea here because it takes
almost 3 hours for the raid to rebuild...

overlay exhaustion solution ???
by John.Florian＠dart.biz
I just had interesting (or incredibly stupid) idea concerning the critical
limitation of the live overlays where the host crashes with bus errors
when the temporary space for the COW is exhausted. Is it possible to use
trim/discard support to mitigate some of the unidirectional growth for
when files are deleted and/or overwritten? Conceptually it seems like it
is a good fit, but I've not investigated the practicality. Just curious
if this has been explored or if there are easily known reasons why this
wouldn't work.

Weird Errors after livecd rebuild
by jose nuno neto
Hi
I have been trying to rebuild one of the latest Fedora Live CD's
Fedora20 Lxde doing my work on a Fedora 19 system
I follow the procedures online doing, Iso mount, squashfs mount, mirror
Iso and Squashfs directories, mount the raw image, do my changes,
rebuild the squashfs and iso.
The problem is that after this process, and even without doing any
change on the raw image, ( i even issue a diff between the original on
the iso file and mine with no changes ) the new LiveCD boots but does
not let me log in. On the desktop login ask's a password and returns to
login screen again and on the console promt does not ask for password
but returns to login
After doing the squashfs a diff reports changes between the squashfs on
original iso and the new one, but it should not no?
Is there a squashfs option I am missing?
rebuild the squashfs on a different version would affect? ( I'm on 19 )
Any ideias on what is happening?
Thanks
