Hi,
I'm attempting to integrate the diskless provisioning feature into the cobbler
as the diskless client management on the cobbler. As the diskless provisioning
tool, we are now using the oneSIS (http://onesis.org/).
So, I have created a couple of patches to collaborate with oneSIS and Cobbler
as work cobbler's sub-command.
If you are interested in this functions, please test an attached patch (see
how-to-use.txt) and any feedbacks are welcome to me. Also, any comments
would be appreciated.
Thanks
-Ihara

Assumption : The distribution is Centos-5.1
1. Download and install onesis with rpm (http://onesis.org/)
2. Apply onesis.patch to cobbler-1.0.3 and build again
3. Download attached "sysimage.conf" (onesis configuration template) and
"dhcp.template.onesis" to your server
4. create diskless's rootFS
# cobbler onesis --rootfs=/var/lib/oneSIS/image/centos-5.1 \
--conf=/tmp/sysimage.conf
this means that rootFS copies to /var/lib/oneSIS/image/centos-5.1 for diskless
client's rootFS
(NOTE: if your rootFS is too big, copy time will be too long and your disk
might be full. The "copy-rootfs" in oneSIS has "--exclude" option that can be
pointed no-copied directory, but it's not used in added the patch, sorry)
5. Modify dhcp.template
# cd /etc/cobbler
# cp dhcp.template dhcp.template.orig
# cp /path/to/dhcp.template.onesis dhcp.template
# vi dhcp.template
modify dhcp.template as your network environment
# cobbler sync
# /etc/init.d/dhcpd start
6. Adding the distribution
# cobbler distro add --name=onesis_centos-5.1 --kernel=/boot/vmlinuz-`uname -r`
\
--initrd=/tftpboot/initrd-`uname -r`.img
7. Adding the profile
# cobbler profile add --name=onesis_client --distro=onesis_centos-5.1
8. Adding the system
# cobbler system add --name=st409 --mac=00:09:3d:00:b0:46 --ip=10.173.7.8
--hostname=st409 \
--profile=onesis_client --kopts="console=ttyS0,9600 selinux=0 root=/dev/nfs"
(NOTE: please change "name", "hostname", "mac", "ip" and "kopts" as your
environment)
9. Restart DHCP and NFS service
# cobbler sync
# /etc/init.d/dhcpd restart
# /etc/init.d/nfs restart
10. Boot the client with PXE
The client will boot up as the diskless client
