Intenet access with LiveCD?
by Jim Dever
Hi,
I was excited to see the release of the Fedora LiveCD as I'm looking
around at different distributions but for some reason I can't get it to
see my internet connection at all.
If anyone could point me in the right direction I'd appreciate it.
NIC: Cnet PRO200WL PCI (not wireless)
Router: Linksys RTP300
Output of ifconfig:
eth0 Link encap:Ethernet HWaddr 00:80:AD:79:95:90
inet addr: 192.168.15.102 Bcast: 192.168.15.255 Mask: 255.255.255.0
inet6 addr: fe80::280:adiff:fe79:9590/64 Scope: Link
UP BROADCAST MULTICAST MTU:1500 Metric: 1

RX bytes: 2597 (2.5 KiB) TX bytes: 0 (0.0 b)
Interrupt: 201 Base address: 0xec00
-----
I noticed that it says UP but not RUNNING.
The Ubuntu LiveCD access the internet just fine so I know it's possible
to MAKE it work. I just like to see it work before making room for a
full install.
I've used Linux before but it's been ages ago and before I had a NIC so
I'm pretty new to this part.
Any help would be appreciated!

Live USB converter script
by Jeremy Katz
When thinking about what we want for booting a live image with a USB
stick, I realized that realistically, we don't want to be distributing a
"live USB" image. Because that requires running dd and destroying
whatever data you already happen to have on your USB stick.
A better choice is to take the live CD image and copy the bits from it
to your USB stick. The result is the attached script. Run it with
arguments of the live CD iso image and the device of your USB key and it
copies over the bits of the live CD onto your USB stick and makes it
bootable. Supported filesystems for your USB stick are vfat/msdos and
ext23.
What do people think? It seems to work from some quick testing and it's
impressive just how much faster it is going from a USB stick.

Caching downloaded RPMs
by J. Christopher Pereira Z.
Hi:
1) I'm building a LiveCD using a remote repository.
Everytime I restart the task, the packages are being redownloaded into the temporal/mounted dir.
Is there any option for caching the downloaded packages?
PS: I'm on FC6 building a FC7 live CD.
2) If there is no option or trick for caching, how can I download only some packages (+ dependencies) into my local repository for building a minimal LiveCD.
Thanks.

Fedora7-Test3-KDE (proposal)
by Sebastian Vahl
Hi.
attached is my current version of a kickstart file for a kde livecd.
I've also written a mail to fedora-devel-list with some explanations.
I would be really grateful for some comments. :)

building fc6 livecds
by Holger Levsen
Hi,
I try to build a fedora6 livecd on fedora6 with the livecd tool.
So I installed livecd and pykickstart from git/cvs, and I'll give you here a
brief rundown of the commands I used, so you can see if the cause for the
error is there:
git-clone git://git.fedoraproject.org/git/hosted/livecd
cd livecd
sudo make install
# install pykickstart with yum, to get the depends...
sudo yum install pykickstart
# livecd-tools need a newer version of pykickstart than fc6 has:
export CVSROOT=:pserver:anonymous@rhlinux.redhat.com:/usr/local/CVS
cvs login
cvs co pykickstart
cd pykickstart
sudo python2.4 setup.py install
Then I modified livecd-fedora-desktop.ks a bit, to use the fc6 repositories
and too later modify the packages etc. I've attached my
livecd-fedora-6-desktop.ks to this mail.
Then I ran the following command:
sudo livecd-creator
--config=/usr/share/livecd-tools/livecd-fedora-6-desktop.ks \
--fslabel=Fedora-6-Test1-LiveCD \
--repo=c6,http://download.fedora.redhat.com/pub/fedora/linux/core/6/i386/os \
--repo=e6,http://download.fedora.devel.redhat.com/pub/fedora/linux/extras/6/i386
Which results in:
[...]

raise Errors.RepoError, ('Cannot open/read repomd.xml file for
repository: %s' % self)
yum.Errors.RepoError: Cannot open/read repomd.xml file for repository: core
I dont think "Repository foo is listed more than once" errors are related, and
I probably just dont know enough about fedora repositories to figure out the
cause and the solution for the repomd.xml problem... greping in the livecd
sources for repomd didnt help :-/ And /var/cache/yum/core/repomd.xml exists.
Any help/pointers certainly welcome, if needed I'll happily provide more
configuration details.
regards,
Holger

[PATCH] Use UUID or label for the filesystem
by Jeremy Katz
The USB key could just have a UUID, so allow that if there's not a filesystem
label. And use vol_id for finding the filesystem type

Doesn't this end up removing the contents of all of your yum cache
(which gets bind mounted from your host)?

[patch 20/20] Clean up mount error reporting
by Mark McLoughlin
BindChrootMount, LoopbackMount, etc. all currently return False when
their methods succeed.
Make them raise an exception when there's an error so we have some
hope of getting a more detailed error message to the user.
Also, make mount() the call to do stuff on all these classes rather
than setup() on some and mount() on others.
