Problem booting live media
by Umarzuki Mochlis
Can't get into GUI, instead weird blocky images. Tried booting with
"vga=normal" and removing the rhgb, but nothing changed. Any help
appreciated.

LiveCD to HDD with CentOS 5.1
by Hoy, Mark
I'm kind of new at this so....
I've built up a CentOS 5.1 LiveCD (thanks everyone) and booted into it
to test it out in VMWare. Nifty stuff.
I've run "liveinst" and indeed it gives me a gui and appears to do the
right thing. I've a number of questions still.
I really like the ability of the "livecd-creator" to resolve the rpm set
that I need. At times I'd like to add a component just to see the rpm
list change requirements without actually building an ISO. Is there a
man page on what livecd-creator can do?
Ideally I'd like to pass a kickstart file into "liveinst" to script what
it does so I don't have to do this numerous times. There is a thread
earlier in this list, but I've not seen any updates on it.
Re: [Fedora-livecd-list] Kickstart ignored?
Thanks in advance.

Fixes to avoid problems on VFAT usb sticks
If we're using a VFAT formatted stick, don't allow an overlay > 2 GB to avoid
corruption. Also, VFAT doesn't really allow for sparse files and the kernel
gets unhappy when you try to make one.

$0.02 idea- persistent desktops
by Douglas McClendon
I think I've mentioned this idea here sometime in the past couple years,
but for various reasons, I'll bring it up now just for the digital record-
feature: persistent desktops
example obvious non-portable implementation:
Use the recently merged persistence feature, along with software suspend
(aka hibernate) to a partition on the liveusb.
What this gets you, is a full system, including running state, on your
LiveUSB. The downside as mentioned is that you are tied to the specific
piece of hardware that you suspended on (swsusp isn't cooler than that
is it?)
dmc implementation:
your custom persisting livecd/liveusb, as part of its default boot
scripts, launches qemu during boot. It launches it from a saved memory
state image, booting perhaps against the same running livecd/liveusb
disk/os. That initial saved memory image is stored on the live media.
That running image is running a vncserver. After the livecd/usb starts
this qemu process from the saved state, it launches a vncviewer as part
of the autologin process, pointing at that server.
Now then, for persistence, during shutdown, a signal is automatically
sent to the qemu monitor to hibernate it (save ram state). Now that new
ramstate file, is stored via the current persistence mechanism (or
perhaps a dedicated partition on the liveusb).
going even further:
it may in some narrow use cases be useful to stare the new ramstate file
as an xdelta diff from the initial one stored on the media.
the persistence data, including these ramstate data could be stored on
public servers, perhaps fedorahosted, or gmailfs, or whatever.

livecd-iso-to-disk remote
by Thiago Braga Santana
Hello to everyone on the list.
I need that the program "livecd-iso-to-disk" is performed remotely, it is
possible?
Explanation: I created an image file of the type .iso with the program
livecd-creator in my PC, now I have a need for this file .iso be applied in
a usbdisk that is connected to another PC.
Anyone can make a suggestion on how I can do this?
Thank you for listening.

LiveCD Workstation
by Tim Wood
In a slightly more fun posting, my LiveCD workstation LiveCD is now
being used to generate LiveCDs. Ah the geekly joy of massive
recursivity. Since Thunderbird's spell checker doesn't like
"recursivity" I may have a name ;-) Anyway, the kickstart isn't quite
ready for public consumption, but soon.

fc7 livecd-creator/liveinst cannot handle yum install in ks file
by jie sun
Hi,
I have some yum install commands in my kickstart file and when I run livecd-creator --config=my.ks in fc7, I got this temp folder left on my box.
/dev/loop0 4128448 139380 3947128 4% /var/tmp/livecd-creator-Sy190t/install_root
And after burn the iso into a CD and install it, I got extra two (first two) partitions on the box.
rootfs ... /
udev ... /dev
/dev/mapper/livecd-rw
1511856 1089732 406764 73% /
tmpfs 1946924 0 1946924 0% /dev/shm
And the liveinst command will fail.
If there is no yum install commands in my.ks file, I only got the following on the box after install with the CD.
/dev/mapper/livecd-rw
1511856 1089732 406764 73% /
tmpfs 1946924 0 1946924 0% /dev/shm
And the liveinst command will success.
There is no problem in fedora 8 even with yum command in my.ks. livecd-creator/liveinst will success in f8
So looks like livecd-creator can only handle simple ks file but can not handle yum install commands in ks file.
Any ideas?
