search for: nfsroot

in Documentation/nfsroot.txt, it says: 1.) Enabling nfsroot capabilities ----------------------------- In order to use nfsroot you have to select support for NFS during kernel configuration. Note that NFS cannot be loaded as a module in this case. The configuration script will then ask you whether you want to use nfsr...

...official Redhat doc through a google search(not hosted by redhat and I cannot find it anywhere on the Redhat site) written by Dave Kline named "Configuring diskless clients with Red Hat Enterprise Linux" from 2011. It seemed to be a work in progress but the steps in it did work for doing nfsroot for one diskless client only. It did not have any explanation for doing read only nfsroot or how to deal with /var for multiple systems. I know there is a file in /etc/sysconfig/readonly-root but I could not get it working correctly. I did kludge together something for /var where during the init pr...

Upon termination, wpa-supplicant brings the wireless interface down and the system hangs being unable to unmount now-defunct NFSroot.

I just checked in changes to kinit, such that it is now a single 29KB executable that replaces the kernel's ipconfig and nfsroot code. The kinit code isn't very elegant, but I figured it was better to save space than to fully generalise it so that it could be extended in a sort of modular fashion. If someone wants modularity, I figure they can spend the few extra KB and run the standalone ipconfig and nfsmount programs...

Hi, I've got another one... NFS error 101 with NFSROOT has been discussed a lot, and hpa gave an answer to it which appears right. It's ENETUNREACH, and I suspect my diskless box does not set its IP parameters right.

....168.16.5 0 0 4.

My /tftpboot/pxelinux.cfg/default file contains the following: nfsroot=192.168.16.5:/export/images/centos51_x86-64,nfsversvers=3,tcp,rsize=32768,wsize=32768,sec=sys ip=dhcp 5.

Hi, I'm trying to deploy some non-linux OS via pxe and I was thinking to just launch CentOS in RAM and then run dd or qemu-img or something like this in order to complete the other OS install via template imaging. My first idea was to build a custom CentOS livecd and use that in combination with pxe kernel parameters, but perhaps there's a better way to do this. Ideas? Thanks, Lucian --
