Hi, please can someone help me...
I have now a new error,
my livecd stops at the end of the linuxrc script!
| Code: |
mount: /dev/hdb is not a valid block device
LiveCD found in /dev/hdc
NET: Registered protocol family 1
umount: /initrd: device is busy
umount: /initrd: device is busy
|
After :
exec chroot . /bin/sh <<- EOF >dev/console 2>&1
exec /sbin/init ${CMDLINE}
EOF
it hangs without an error...
[Edit]
When i try to start /sbin/init manually i get this message:
| Code: |
init: timeout opening/writing control channel /dev/initctl
|
Ha! now my livecd works.
Without the nvidia drivers but it works...
[edit]
How do i get the nvidia drivers to work?
The nvidia-settings program says "The OpenGL extension 'GLX' is not suported by the X server"...blah blah
and glxinfo says: "error while loading shared libraries: libnvidia-tls.so.1: cannot handle TLS data"
I tested the CD on another PC with ati-drivers and it works, but why not the nvidia-driver?
[/edit]

Hey just wanted to say thanks for all your hard work!!
Now I have a little bit of a modified project. I am using the Lived layout to make some routers on 512MB flash Cards. Everything seems to be working up to a point. Here's my grub config:
| Code: | default 0
timeout 5
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title=Gentoo Linux
root (hd0,0)
kernel /boot/vmlinuz root=/dev/ram0 rw init=/linuxrc
initrd /boot/initrd
|
I had to manually install Grub on the Memory card and it's an IDE card interface so its located at /dev/hda1.
I get the boot screen and initrd seems to work fine but I keep getting this error when it attempts to run the "/linuxrc" init script.
| Code: |
Failed to execute /linixrc. Attempting defaults...
Kernel Panic - not syncing: No init found. Try passing init= option to kernal. |
here is my linuxrc file:
| Code: | #!/bin/sh
export PATH=/bin
# Get kernel CMDLINE

Now if I change the init= option to /bin/sh, I can go into my initrd just fine, I can even go through the steps of the linuxrc file manually and get the sucker to start booting. I can also run the /linuxrc file with the ./linuxrc at the terminal, but it wont start booting. i suspect it has something to do with the CMDLINE variable not being correct (/bin/sh instead of /linuxrc) My questions are:
-Why can't it execute /linuxrc script, when I can execute it manually?
-How accurate is the error message, is it possible it's executing the linuxrc script and just failing somewhere in there?
-Got any ideas to help out my project?

OK well I changed my linuxrc file a bunch and now I finally got it to boot. It looks like if the linuxrc doesn't run correctly you get that very generic error during booting. Hope maybe it will help someone else know where to look in the future.

| i followed the same guide from the wiki, step by step, but when i try to boot the livecd, the cdrom medium is found at /dev/iseries/vcd* , which is not true, so the booting process couldn't continue... any suggestion ? |

Hy,
It's gonna be the 6 image that I'm creating (genkernel and squashfs time, it's long) and I'm crazy ; it's not working.
Resume :
1. Installation Gentoo OK
2. Chroot OK
3. emerge system and tools OK
4. emerge gnome-light OK
5. configuring system OK
6. configuring kernel OK
7. clean OK
8. bootloader OK
9. final clean and build OK
Testing iso with vmplayer CRASH :
::Scanning for dm-mirror...dm-mirror loaded
>> Activating udev (green, i guess it's ok)
>> Making tmpfs for /newroot (green)
>> No bootable medium found. Waiting for new devices (yellow)
!! Could not find CD to boot, something else needed !
>> Determining root device (green)
!! The root block device is unspecified or not detected.
Please specify a device to boot, or "shell" for a shell...
I don't understand where I made a mistake. I search the web for explanation, read this thread but without having answear. I'm trying to use unionfs instead of tmpfs but I don't think problem come from here.
my question if anybody could help me :
1. At what time of boot process this error occures ? (kernel loading, root filesystem switching, ...) As I'm not a geek of booting process, I can't figure out what's happening and where to search...
2. I read the note : Writeable /home directories with genkernel and unionfs in the How to TALK and i don't kow how to create the livecd.unionfs ?? Actually I used mksquashfs with a file named livecd.unionfs but I'm not sure. I read the exemple of Union-fs site and it doesn't seem to work like that but I don't find how to create an image of a directory (is mounting a directory with unionfs and adding branch to it is the way to create the livecd image ?)
3. What is exactly the difference between /dev/loop0 in etc/fstab and the /dev/ram0 in grub config ?
you and your help is really welcome  |

I had this exact problem, it turns out that I didn't compile some options into the kernel (they were modules). I changed a few options so I don't know which ones they were exactly, but I think it was that I didn't compile the ISO9660 filesystem into the kernel (Filesystems -> CD-ROM/DVD Filesystems -> ISO9660 -> "ISO 9660 CDROM file system support"). If that doesn't fix it, go through and look for options that regard a CD/DVD or CD/DVD drive, etc.
EDIT: Oh.... rather old post :p |

Alright I've built my livecd and am testing it out on vmware. Grub launches and loads the initrd and then I run into this error
No filesystem could Mount root, tried: ext3 ext2 squashfs msdos vfat iso9660 ntfs
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)
Here is my linuxrc script:
| Code: | #!/bin/sh
export PATH=/bin
# Get kernel CMDLINE
mount -t proc none /proc
CMDLINE='cat /proc/cmdline'
umount /proc
# Mount option
# mount -t iso9660 -r /dev/hdc /cdrom > /dev/null 2>&1
# Mount CD device
CDROM=""
for x in hda hdb hdc hdd
do
mount -t iso9660 -r /dev/${x} /cdrom > /dev/null 2>&1
if [ "$?" = "0" ]
then
CDROM="${x}"
break
fi
done
# CD not found

then

exit
fi

cd /newroot
pivot_root . newroot
exec chroot /newroot /bin/sh <<- EOF >dev/console 2>&1
exec /sbin/init ${CMDLINE}
EOF
|
My other question is do i leave /dev/loop0 mount at /mnt/initrd?
Any clues to what i'm doing wrong? |

Sorry for crossposting The following is taken from Talk page, I have the same problem:
| Quote: | Problems with Symbolic Links
After "Copying read-write image ...", when, I think, the linuxrc script starts to run, it starts giving me a LOT of errors in the form : "ln: creating symbolic link `/var/lib/init.d/softscripts.new/clock` to `/etc/init.d/clock`: No such file or directory". The same goes to all the files in init.d, such as hostname, domainname, net.lo etc... Does anyone have a clue as to what is the problem? I tried to switch to init=/bin/sh instead of the linuxrc and it still boots like this. I followed the instructions on the site exactly as it is written and I fail to see where the problem is. can anyone please help?
* [mapelo] I have the same problem, and all files and directories in tmpfs (etc,var,...) are NOT write access, only read access. |
Is there any way to solve it?

followed the how-to as closely as I could. I get a kernel panic when trying to execute /linuxrc
(fyi: I'm typing this out from qemu...)

linuxrc is copied identically from the OPs how-to...
(all file system references below are while chrooted in...)

|
If I press 'e' while in grub menu and edit the kernel's init parameter to '/bin/sh' I get the same error as above, but instead of not being able to execute /linuxrc, it says it is unable to execute /bin/sh ... however
| Code: | mutt / # stat /mnt/initrd/bin/sh

After being stumped for a week, I finally figured it out.
but first, a bit of background.
I had, as instructions said, copied /bin/sh /bin/cat ...etc to the initrd fs.
Also, I did ldd /bin/sh, copied the resulting stuff from lib... and the same for everything in bin.
The idea was to copy ALL of bin and ALL of lib into the initrd. While I had to omit some of the clearly unneeded things from bin, it all fit in a 7MB initrd.
And most importantly, it works!!
So, clearly the problem was that I was not careful enough when copying the lib stuff specified by ldd.
What a waste of a perfectly good week. sheesh. |

[quote="veezi"] | Code: | mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot -boot-load-size \

OK. So -b is to produce a bootable El Torito CD....
I think its -B for sparc but where do I get the boot image from ??? |

| It would be nice to have a tutorial that explains how to make a livecd from windows xp. All the ones I can find already assume you have at least some kind of linux distro installed or usually gentoo already. |

I had EXACTLY they same problem you did, but I found a different fix without copying everything into bin/lib. This might be obvious, but it took me a day to figure it out - if you have a 64 bit system, copy everything into /lib64 and create a symlink /lib pointing to /lib64. Most of my binaries were linked to the lib64 directory, so it couldn't find them on boot because I just had a /lib directory in my initrd. |

and
| Code: | | rc-update add autoconfig default |
But, when i write hwsetup & mkxf86cinfig, startx works.
startkde write error: no space Ieft on device
What do i wrong, or what i should do?
Thanks! Sorry, my english isn`t very good..

Remove mkxf86config from default. Autoconfig will run it automatically.
NOTE TO SELF (for future reference):
Add noresume to the kernel argument list to prevent spurious | Code: | | ls: : No such file or directory |
messages from showing up during boot. |

My turn to bump an old topic.
Seeing as this guide is older than written word itself, I've had to modify it a lot to get it working for me.
Anyways, Im having a problem mounting the CD-ROM drive as part of linuxrc's script:
| Code: | * Executing linuxrc
* Mounting /proc
* Unmounting /proc
* Mounting optical device
mount: /dev/hda is not a valid block device
mount: /dev/hdb is not a valid block device
mount: /dev/hdc is not a valid block device
mount: /dev/hdd is not a valid block device
*** NO optical device found, dropping a shell ***
sh-3.2# _ |
Im really not sure why Im getting these errors. My kernel (2.6.24-gentoo-r4) is (as far as I know) setup properly with the right items built in, rather than modules. My linuxrc file looks like this:
| Code: | #!/bin/sh
export PATH=/bin
# Get kernel CMDLINE
echo " * Mounting /proc"
mount -t proc none /proc
CMDLINE=`cat /proc/cmdline`
echo " * Unmounting /proc"
umount /proc
# Mount CD device
echo " * Mounting optical device"
CDROM=""
for x in hda hdb hdc hdd cdrom
do
mount -t iso9660 -r /dev/${x} /cdrom
if [ "$?" = "0" ]
then
CDROM="${x}"
break
fi
done
# CD no found
if [ "${CDROM}" == "" ]
then
echo " *** NO optical device found, dropping a shell ***"
exec /bin/sh
exit
fi
# Mount root and create read-write directories
echo " * Mounting root file system"
mount -t squashfs -o loop /cdrom/files/source.img /new > /dev/null 2>&1
echo " * Mounting /var"
mount -t tmpfs -o size=32m none /new/var > /dev/null 2>&1
echo " * Mounting /etc"
mount -t tmpfs -o size=32m none /new/etc > /dev/null 2>&1
echo " * Mounting /tmp"
mount -t tmpfs -o size=32m none /new/tmp > /dev/null 2>&1
echo " * Mounting /root"
mount -t tmpfs -o size=32m none /new/root > /dev/null 2>&1
echo " * Filling directories"
cd /new/var && tar xpf /cdrom/files/var.tar > /dev/null 2>&1
cd /new/etc && tar xpf /cdrom/files/etc.tar > /dev/null 2>&1
cd /new/root && tar xpf /cdrom/files/root.tar > /dev/null 2>&1
# Pivot root and start real init
echo " * Attempting pivot"
cd /new
pivot_root . newroot
exec chroot . /bin/sh <<- EOF >dev/console 2>&1
echo " * Starting init"
exec /sbin/init ${CMDLINE}
EOF |
