Recently, I was able to create a workable Centos 4.4 "Live USB" on my 1G Lexar Firefly pendrive using the steps in http://linux.web.psi.ch/livecd/usbdisk.html. At the moment, it is doing its job, so I probably won't focus too much more on it. One thing that is annoying, although doesn't cause a problem is that on powerdown and reboot, the cd rom drive ejects - of course, there is no CD in it!
My ultimate goal is to get a standard, updatable 4.4 install onto my 4G Firefly, I am at a loss as to why I get the following errors:
***************************************
Booting 'CentOS-4 i386 (2.6.9-42.EL)'
root (hd0,0) Filesystem type is ext2fs, partition type 0x83 kernel /vmlinuz-2.6.9-42.EL ro root=LABEL=/ rhgb quiet [Linux-bzImage, setup=0x1400, size=0x16dd65] initrd /initrd-2.6.9-42.EL.img [Linux-initrd @ 0x1fefe000, 0x612ef bytes]
Uncompressing Linux... Ok, booting the kernel. Red Hat nash version 4.2.1.8 starting mkrootdev: label / not found mount: error 2 mounting ext3 mount: error 2 mounting none switchroot: mount failed: 22 umount /initrd/dev failed: 2 Kernel panic - not syncing: Attempted to kill init!
***************************************
This is what I did:
- installed CentOS 4.4 from CDs using "expert mode" - grub bootloader - /dev/sda1 mounted on /boot 100M - /dev/sda2 mounted on / 3.9G - no swap - server install (w/gdm)
It was suggested that I may be having an issue with USB drivers not getting installed, so I ran mkinitrd including them. I also uncompressed initrd.gz and tried to add them manually - I had no luck with either method.
Since I am by no means a Linux expert (my background is in data and voice networking), any and all suggestions and URLs will be appreciated!

Hello,
It sounds like you forgot to label your / partition (/dev/sda2) as "/".
As a workaround, interrupt the grub loader and edit the boot command line from kernel /vmlinuz-2.6.9-42.EL ro root=LABEL=/ rhgb quiet to kernel /vmlinuz-2.6.9-42.EL ro root=/dev/sda2 rhgb quiet
you should then be abble to boot the kernel and get a minimal shell, but probably failed to mount "/" ie finish the boot process : /etc/fstab may also mention "LABEL=/" instead of "/dev/sda2" for / FS.
To fix it, 2 solutions:
* once booted, (mount and) modify /boot/grub/grub.conf to modify the kernel boot parameters as did to boot and also the /etc/fstab.
* or label your root partition as "/" to match the kernel options in grub. the command to do it is: e2label /dev/sda2 "/" I'm not sure you can do it on your running system (ie /dev/sda2 mounted), you should use a rescue system to do it.
Hope this help,
Pierre Bourgin
