Hi all,

How to patch and rebuild bootstrap image right in place on master node:

On master node as root:

1. Unpack initramfs.img

`cp /var/www/nailgun/bootstrap/initramfs.img ./`
`mkdir initramfs`
`cd initramfs/`
`cat ../initramfs.img | gunzip | cpio -imudv`

2. Edit /initramfs/opt/nailgun/bin/agent

`vim /initramfs/opt/nailgun/bin/agent`

Locate
44 REMOVABLE_VENDORS = [
45   "Adaptec",
46 ]

and add necessary VendorID.
You may run ohai > ohai.log inside bootstrap to see which VendorID are
visible for Agent.


44 REMOVABLE_VENDORS = [
45   "Adaptec", "IBM", "ServeRA", "Vasya Pupkin"
46 ]

Save changes and exit editor.

3. Assemble new initramfs.img

`cd initramfs/` or where you did unpacked it
`find . -xdev | cpio --create --format='newc' | gzip -9 >
../initramfs.img.updated`

4. Install updated initramfs.img

`rm /var/lib/tftpboot/images/bootstrap/initramfs.img`
`rm /var/www/nailgun/bootstrap/initramfs.img`
`rm /var/www/cobbler/images/bootstrap/initramfs.img`

`cp ../initramfs.img.updated  /var/www/nailgun/bootstrap/initramfs.img`
`chmod +r /var/www/nailgun/bootstrap/initramfs.img`
`cobbler sync`

That's all.
Cobbler Sync should re-create both mandatory hard-links:
/var/lib/tftpboot/images/bootstrap/initramfs.img
/var/www/cobbler/images/bootstrap/initramfs.img

Sometimes cobbler stops booting nodes after sync - please reboot master
node in such case.
Now, you may boot your nodes to updated bootstrap.

Please also note - you should somehow update nailgun-agent package in local
repositories if you want new agent to be automatically installed to
deployed nodes.
Otherwise deployed nodes would report no disks.
Or you have to get the updated packages and manually install to all
necessary nodes.


Do you still want me to assemble new patch for you?


Kind regards,
Miroslav
