Customize login prompt text in Yocto

Hello,

Normally, when building e.g., a console-based image using Yocto, you will get at caption text "Poky Reference Distribution"... at the login prompt. Is it easily possible to change / customize this caption text,

and in such a case, which Yocto package / recipe requires change. Any information would be greatly appreciated.

Best regards,

Andreas Enbacka

the information shown is from the file /etc/issue. You can for example do post-processing on this file and change the information. You can add this to your image recipe.

update_issue() {
    echo "Your text" > ${IMAGE_ROOTFS}/etc/issue
}

ROOTFS_POSTPROCESS_COMMAND += " update issue; "

Hi Peter,

Thanks a lot for the info, I will try it out.

The more "yoctonic" way of setting this is to modify the DISTRO_NAME variable, which is set in the distro configuration file e.g. poky.conf. If you are building your own distro it you may want to derive your own distro configuration file from the ones that Poky provides. There you can also set other variables such as DISTRO_VERSION, MAINTAINER, etc.

Hello,

What is the correct way to override poky.conf? I tried adding a new file custom-poky.conf into meta-yocto/conf/distro, including the poky.conf file and overriding e.g., DISTRO_VERSION. Is this the correct approach, or is some other changes required as well?

Best regards,

Hi Andreas,
In general, you should not add your changes to poky directly, or any of the other provided layers.
In this case the 'permanent' way to do this is to produce your own distribution layer but the quick alternative is to set the variable in conf/local.conf. Regards,Chris
