using %post -nochroot

[dwoody1]

Using livecd-creator (ver. 13-4) I have made a livecd with a recompiled kernel 
and it boots and works. I am now at the point of copying some configuration 
files from the hard drive to the livecd using the livecd-creator program.

The following method works:
%post
echo "nameserver 10.10.2.99" > /etc/resolv.conf

but I would like to use:
%post -nochroot
cp /etc/resolv.conf > /somewhere/etc/resolv.conf

I have not been able to determine what 'somewhere' should be.

I have never programed in python but I have looked through the livecd-creator 
program and made several 'best' guesses but I have not found anything that 
works. I have also searched the internet and I have found nothing that 
addresses this.

The documentation on 
http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/sysadmin-guide/s...
says to:

%post --nochroot
cp /etc/resolv.conf /mnt/sysimage/etc/resolv.conf

/mnt/sysimage does not exist.

Any help will be greatly appreciated,

David

/mnt/sysimage is only relevant for anaconda installs -- creating live
images on a real system, we can't guarantee that /mnt/sysimage exists or
is being used for this purpose.  Thus, you can instead use
$INSTALL_ROOT.  Which iirc, I also added to anaconda in F8

So, dcw would do this:

%post -nochroot
cp /etc/resolv.conf > /$INSTALL_ROOT/etc/resolv.conf

Correct?

Yeah, documentation is lacking right now.  I see that Tim and Jeremy 
answered this while I was pasting this mail together, but since this 
response adds a bit more, I'll go ahead and send it.

Here is the same help I just gave Mike Dickson a couple days ago-

--------------
1) to add some arbitrary file (300M mpeg) to the resulting LiveCD ISO image-

in your own config/kickstart, you can add a section like the following
(note, you can just add this, as there can be multiple of these %post
sections)

%post --nochroot

mkdir $INSTALL_ROOT/usr/share/extramedia
cp /home/mdickson/some.mpeg \
$INSTALL_ROOT/usr/share/extramedia/

mkdir $LIVE_ROOT/momedia
cp /home/mdickson/someother.mpeg \
$LIVE_ROOT/momedia/

%end

Note, the first part, will add the file to the root filesystem that is
visible when you boot up the livecd/usb.  And as a result will be
compressed during the build process (but obviously not well, as mpeg is
already compressed as much as it can).

The second part (using LIVE_ROOT instead of INSTALL_ROOT), will add the
file to the cdrom filesysem, uncompressed.  As such, the user could for
instance easily see the file if they dropped the cdrom into a windows
system (on the cdrom, under the top level folder 'momedia').
