| cmack2 | How is the kernel for the ubuntu-server ISO compiled? Are there scripts for this? | 20:17 |
|---|---|---|
| CarlFK | cmack2: I am sure it is a package, and I think the -server and desktop now use the same kernel | 20:19 |
| cmack2 | Which package? | 20:20 |
| CarlFK | linux-image-3.13.0-24-generic (that is what is installed on my desktop ) | 20:23 |
| CarlFK | I am pretty sure, but it would be good if you have a server install handy: apt-cache policy linux-image-3.13.0-24-generic | 20:24 |
| cmack2 | The vmlinuz file from http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-3.13.0-24-generic_3.13.0-24.47_amd64.deb differs from vmlinuz file from http://releases.ubuntu.com/14.04/ubuntu-14.04-server-amd64.iso | 21:03 |
| cmack2 | It does not look like the kernel for ubuntu-14.04-server-amd64.iso comes from the linux-image-3.13.0-24-generic_3.13.0-24.47_amd64 package | 21:04 |
| cmack2 | Where else could the kernel in ubuntu-14.04-server-amd64.iso come from? | 21:07 |
| infinity | cmack2: It's 24.46, not 24.47 | 21:08 |
| infinity | 24.47 was a post-release security update, we didn't hop in a time machine to build the release ISOs with it. ;) | 21:09 |
| cmack2 | The vmlinuz file in the server ISO seems to have additional content at the end than the vmlinuz file in linux-image-3.13.0-24-generic_3.13.0-24.46_amd64.deb | 21:12 |
| cmack2 | It looks like a secure boot signing in the server ISO | 21:13 |
| cmack2 | How is this added? | 21:13 |
| xnox | linux-image-signed (well the real one) does sbattach to add back the secure-boot signature to the kernel. | 21:14 |
| xnox | in postinst. | 21:14 |
| cmack2 | xnox: What is "the real one" of linux-image-signed? | 21:28 |
| xnox | cmack2: linux-signed-generic is just a metapackage which depends on a package with a signature for a matching kernel. | 21:31 |
| xnox | e.g. linux-image-3.10.0-3-generic 's signature is in linux-signed-image-3.10.0-3-generic | 21:32 |
