Hi folks,
I've followed a set of instructions I found on http://www.linuxtopia.org/online_books/centos_linux_guides/centos_enterprise... which describes using system-config-netboot to set up PXE booting.
I used a CentOS-4.3 install (custom, all options de-selected, then anaconda-busybox installed after the fact) as a reference/base. I followed the instructions, extrapolating a bit as the window defining the diskless client has more options than those presented in the example.
When I boot the PXE client, it does the pivot root operation, and finally concludes with:
SELinux: Disabled at runtime SELinux: Unregistering netfilter hooks
...at which point it hangs for ever.
I have tried performing a yum -y update on my reference system, then recreating the root mount point, but it fails the same way.
I should probably mention that both the reference and diskless client are identical hardware, and that the hardware has successfully PXE booted a diskless OS (a RedHat 8.0 as it happens) in the past.
The lack of any information on the web implies that I'm doing something trivially incorrect, can anyone tell me what it is?
Thanks for any hints or pointers you can provide.

I just can say that I had the same problem with centos 4.5. Seems that centos is a little buggy on this.

and which bug is that again in the centos bug tracker?

I personally didn't enter a bug, as my research on the subject showed a lot of discussion in the Fedora distro as to what this tool was really supposed to be doing. It isn't included in the upstream v5 release, but is due to get re-included at a later time once things are sorted out.
I think this is rather like the Xen offering -- the bare bones of a good/useful idea that needs more work before it's ready for general use. I'm sure it will be usable in the future, just not today.
I have access to, but have not tried, the upstream product. If I get a chance I will and if it functions differently than the CentOS offering I will enter a bug; any other problems are more likely upstream problems.

Hi, i'm not familiar with precisely this solution, but i've been solving something similar few months ago...
I think the best thing you should do when searching for the reason is going step after step after the mount of pivot root. There must be some script on the tftp server, where the mount of the pivot root and snapshot is executed... so find it and then start shell right after it.
This gives you enough space for finding what is happening and trying how to fix or find the bug (if it is a bug ;-))
