Layer versions at runtime

Layer versions at runtime

I've noticed that bitbake prints the git commit versions of the layers when
the build starts.

meta-python       = "HEAD:b40116cf457b88a2db14b86fda9627fb34d56ae6"
meta-mender-core  = "HEAD:c3b1b465ce3a27fc7b03a6b7ef596348835cff57"
meta-go           = "HEAD:514b2a80a2a4235687e92fb28328bb3e7c2d6c74"

Does this information find it's way into the rootfs?
If not, any suggestions on how to achieve this?

The goal is to have this info available while the image is running.

Be Well,
Alan

Hi,

That's easy to do :


do_install_append () {

     for layer in ${BBLAYERS}; do
         cd $layer
         echo -n "$(basename $layer) = "  >> ${D}${sysconfdir}/gitinfo
         git rev-parse HEAD >> ${D}${sysconfdir}/gitinfo
     done
}


add it in a recipe or add it to os-release.bbappend

Or better yet use

to get:

DISTRO = nodistro
