Hi all

I follow this wiki http://en.gentoo-wiki.com/wiki/Build_Yo ... or_LiveDVD to create a live-usb
i used genkernal as well but i cant mount to squashfs image

my grub settings are

title gentoo
root (hd0,0)
kernel /boot/kernel-genkernel-x86-2.6.29-gentoo-r6 root=/dev/ram0 real_root=/dev/loop0 looptype=squashfs loop=livecd.squashfs initrd udev cdroot slowusb nodevfs
initrd /boot/initramfs-genkernel-x86-2.6.29-gentoo-r6

but i get this

>> Activating mdev
>> Making tmpfs for /newroot
>> Looking for the cdrom
>> Determining root device...
>> Determining looptype ...
!! Invalid loop location: /livecd.squashfs
!! Please export LOOP with a valid location, or reboot and pass a proper loop=...
!! kernel command line!

If anyone has any ideas ?????

Thanks

http://www.gentoo.org/doc/en/liveusb.xml is the "official" guide

http://www.sysresccd.org/Sysresccd-manu ... _USB-stick "the better idea"

This stuff is located where a kernel argument should be

looptype=squashfs loop=livecd.squashfs initrd udev cdroot slowusb nodevfs

but there are no valid kernel arguments in the list.

http://www.mjmwired.net/kernel/Document ... meters.txt

some are valid genkernel arguments but they need to be used when invoking genkernel.

I think the broblem is at the genkernel linuxrc script ,when i get the shell from the failure of live.squashfs ,i mount manualy the /dev/sda1 to /newroot/mnt/cdrom and then the livecd.squashfs to /newroot/mnt/livecd ,exit from the shell and then boots fine.
