Adding extra files to the existing packages

If we need to include an extra configuration file, we should use FILESEXTRAPATHS, as explained in the previous example and shown in the following lines of code:

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PV}:" 

SRC_URI += "file://newconfigfile.conf" 

do_install_append() { 
    install -m 644 ${WORKDIR}/newconfig.conf ${D}${sysconfdir} 
}

The do_install_append function appends the provided block below the metadata already available in the original do_install function. It includes the command needed to copy our new configuration file into the package filesystem. The file is copied from ${WORKDIR} to ${D} as the directory used by Poky to build the package and the destination directory used by Poky to create the package. The ${sysconfdir} directory is the system configuration directory (usually with /etc).

Tip

We should use the variables provided on top of poky/meta/conf/bitbake.conf instead of pointing to hardcoded paths. For...
