 Posted: Tue Mar 12, 2024 2:03 pm Post subject: Naming a custom kernel |
 |
|
Hi everyone!
i have managed to build my own kernel! (I was trying in https://forums.gentoo.org/viewtopic-t-1167661.html previously).
I have given my kernel a custom name, but i only get
| Code: | $ uname -r
6.6.21-gentoo-gentoo-sources
|
this weird naming.
I think i got the CONFIG_LOCALVERSION="-r3" right, but I do not now what to with CONFIG_DEFAULT_HOSTNAME. Is it just the default file for /etc/hostname?
How can I remove double "gentoo" from my config and customize the name? |

setan,
I think we touched o the double gentoo is you previous topic.
The Makefile provides
| Code: | # SPDX-License-Identifier: GPL-2.0
VERSION = 6
PATCHLEVEL = 7
SUBLEVEL = 6
EXTRAVERSION = -gentoo
NAME = Hurr durr I'ma ninja sloth |
That's 6.7 from Linus SUBLEVEL =6 from Greg/Sasha, for 6.7.6 and -gentoo from Gentoo.
That's gets you 6.7.6-gentoo.
You will have set CONFIG_LOCALVERSION="gentoo-sources" in the kernel configuration file, so in all concatenated together for the final kernel name.

As a example: | Code: | amd64 /usr/src/linux-6.8.0-gentoo-std # uname -r
6.8.0-gentoo-std
amd64 /usr/src/linux-6.8.0-gentoo-std # head -6 Makefile
# SPDX-License-Identifier: GPL-2.0
VERSION = 6
PATCHLEVEL = 8
SUBLEVEL = 0
EXTRAVERSION = -gentoo
NAME = Hurr durr I'ma ninja sloth
amd64 /usr/src/linux-6.8.0-gentoo-std # grep "\-std" .config
CONFIG_LOCALVERSION="-std" |

@NeddySeagoon,
> I think we touched o the double gentoo is you previous topic.
That's true. I did not think that this would be in the makefile...
Thank you both, this explains this in detail.
Now, do you think that having multiple custom kernels (like linux-zen and normal linux)?
Is it even doable? |

setan,
Yes. They will have different names. If they don't CONFIG_LOCALVERSION is yours to play with when you configure the kernel.
You can edit the names in the Makefile if you wish but you need to do that every version bump, so that should be avoided.
The kernel knows its own modules by the full name. Look in /lib/modules.
You will have a 6.6.21-gentoo-gentoo-sources/ dir there. Well, you will if you have any kernel modules.

Directories ending with gentoo are untouched ebuilds.
gentoo-xxx are just directories for .config with CONFIG_LOCALVERSION="-xxx" set & a few other files.
Using home brewed scripts to bring .config to the matching gentoo-sources directory to do whatever I need.
home brewed script to also migrate existing gentoo-xxxx/.config ro new genoo-yyyy/.config, make & install
Mainly gentoo-sources here. But this is not required once scripts are well set.
As modules are concerned, linux-6.8.0-gentoo-std modules will be in /lib/modules/6.8.0-gentoo-std because of CONFIG_LOCALVERSION="-std"
