Know to excuse to my poor man ingles. I have followed all the passages without difficulty. I run the script /build, appears the message that it indicates to run /before-build and after which prompt is executed, been and nothing but. Wait for all the night, thinking that it had been time to arm iso, but never was created. Now I ask, can be that this happens, because i make the distro in the /home/usuario directory, like root? I clarify that in script, it changes the necessary thing so that works.

Thank

Sepan disculpar mi pobre ingles. He seguido todos los pasos sin dificultad. Corro el script ./build, aparece el mensaje que indica correr el ./before-build y luego de que se ejecuta, queda el prompt y nada mas.
Espere toda la noche, pensando que llevaba tiempo armar la iso, pero nunca se creó.
Ahora pregunto, ¿puede ser que esto ocurra, porque arme la distro en el directorio /home/usuario, como root?
Aclaro que en el script, cambie lo necesario para que funcione.

Gracias

PD: Si alguien habla español, se lo agradeceré.

I have created livecd's using this method and they are relatively successful

However I cannot get one to automount flash devices and successfully mount fdd in user mode (not as root) by successfully i mean the folder mnt is not accessible even if you can mount the device

Hi,

I created a livecd and it's almost working.
If I boot, I get the error message

Thanks for the howto!

I am having a problem removing gcc from my livecd's. The problem is that python is linked to libstdc++ in /usr/lib/gcc-lib, rather than /usr/lib:

ahh, my mistake. the left hand side of ldd output shows which libraries a binary is linked to, and the right hand side shows how they resolve on your individual system.

thus, I can just copy the libs like so:

Looks like it's my turn to add to this massive discussion. I'm having a few problems with mkisofs. Here is what I get after running the build script, or running each part of the build script manually.

# mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot -boot-load-size 4 -boot-info-table -iso-level 4 -hide -c boot.catalog -o /root/livecd.iso target/
Warning: Creating ISO-9660:1999 (version 2) filesystem.
Warning: ISO-9660 filenames longer than 31 may cause buffer overflows in the OS.
mkisofs: No such file or directory. Invalid node - boot.catalog

I'm done banging my head on the wall, but I might start up again. I spent 4 hours last night trying to figure out why the "cp" step in the build script kept hanging. I mean all it's doing is copying, but 3 hours later, it was stuck with no hard drive activity. I rebooted and I was good to go.

Any takers on my issues?

hi, i want to ask an interesting question. is it possible to create a livecd that is using my curent configurations? a stage 3 cd with all that i compiled already (something like a backup)?

Yeah ... search this thread. I vaguely remember there being a link out there to some tools that you can use on any distribution to make a livecd based on your install.

because it chroots you into the livecd target directory, and the script can't interact with the chrooted environment.

BeteNoire · Veteran Joined: 25 Sep 2005 Posts: 1827

Uhm... so what should I do? Exit chroot and restart "build"? But how to make it run from the point it ended?

Hello,
in the howto build a liveCD from scratch, i think you forget to delete the line mkdir newroot
because it's just use in the deprecated function to build initrd ?
Great job !
Loux
PS : i'm creating a little script to build a livecd with your howto, i will publish it

Hello,
i'm trying to follow the steps of the howto but during the boot stage, i have the following error :
Booting (initramfs)......
/bin/sh: error while loading shared libraries: cannot make segment writable for relocation: Permission denied

the script that i use to build the livecd and the config of the kernel are in my server :
http://loux.homelinux.org/~loux/livecd/
(i use a lot of sudo because i don't want running my script whith sudo to not execute action i don't want !)
thanks
loux

Hi everybody;
Very usefull howto and lot of comments.
However I didn't find the solution to my pb.

My system loops for ever... every seems to work fine; but at the end of the linuxrc, back to grub....

When i play with /bin/sh instead of linuxrc, i reach the end of the process:

Instead of "exec /sbin/init ${CMDLINE}" use only "exec /sbin/init".

if the cd doesnt even start to boot, the error has to be somewhere in the build script or while it is running right?

burned the cd with this command, is that okay ?

That's ok, I'd be more concerned with the mkisofs command you used. Does grub run normally?

Hi, thks for the quick response.

Yes grub boots fine and allows me to boot my "installed gentoo", windows or the "live cd".
And with the linuxrc from the howto, it loops for ever.

I will try to modify the last line and will remove the $CMDLINE parameter.

I kepp you informed.

Lucio

I'm wondering why doesn't anybody answer my question? Was it so "lame"?

So... how most people here are able to make their livecds following this howto? I am not and stuck with no info about what to do.

Hello,
for 'lame' : i found that on web -> gentoo -> on-line database->lame -> mp3 encoder !

i don't know if it is a good idea to unmerge so packages before making the squash file in the howto,
for example linux-headers, gcc, automake, autoconf ... ?
