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...

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.

Hi:
Thanks for the advice. I think I did try this (actually, I believe when I
went through the CentOS install (graphical if it makes any difference) by
default it labelled it as /. I am hoping tonight or tomorrow to try to do
another install and will give it a shot!

I went ahead and verified the labels on my partitions, and /dev/sda2 is labelled "/" and /dev/sda1 has a label of "/boot". Like I previously mentioned, I believe /boot is fine since grub loads - I am still at a loss as to why it can not see /. I installed the pendrive into my home PC running 4.4 and /dev/sda2 looks fine. I also ran fsck on it and it is clean. A while back, it was suggested that I run mkinitrd and include the USB drivers. I tried this, but it still wasn't recognized. If anyone can help me get pointed in the right direction, it will be greatly appreciated. Thanks!

Not a problem. If I need to add USB functionality into the kernel - the next question is what are the steps involved to do this? I was under the impression that running mkinitrd was all that needed to be done. Of course, I did run it and still got the same errors.
