Bitbake personalizado bbapend no agrega correctamente el archivo fstab mender - linux, sed, embedded, yocto, bitbake

Estoy usando github.com/mendersoftware/meta-mender en mi compilación yocto. Quiero editar / etc / fstab usando sed con un archivo bbappend en mi propia capa. Específicamente, meta-mender está suministrando su propio archivo fstab y lo está editando con un base-files_3.%.bbappend, y solo quiero eliminar el auto palabra clave del / etc / fstab generado.

El problema es que cuando proporciono mi propio bbappend(mi capa tiene una prioridad más alta que el metamender) en mi capa para base-files_3.%. bbappend, el metastader fstab no parece haber sido creado, y el stock de open-embedded es en cambio.

Aquí está mi meta-layer / recipes-core / base-files / base-files_3.%. Bbappend:

do_install_append(){
sed -i -e "s$.*@MENDER_BOOT_PART@.*$@MENDER_BOOT_PART@   /uboot           @MENDER_BOOT_PART_FSTYPE@       defaults,sync    0  0$" ${D}${sysconfdir}/fstab
sed -i -e "s$.*@MENDER_DATA_PART@.*$@MENDER_DATA_PART@   /data     @MENDER_DATA_PART_FSTYPE@       defaults         0  0$" ${D}${sysconfdir}/fstab
}

Si corro bitbake -e base-files, luego busque la función do_install, puede ver claramente que mi sed los comandos se agregan correctamente a meta-mender / meta-mender-core / recipes-core / base-files / base-files_3:

Y sin embargo, mi / etc / fstab se ve así:

# stock fstab - you probably want to override this with a machine specific one

/dev/root            /                    auto       defaults              1  1

tmpfs                /var/volatile        tmpfs      defaults              0  0

#/dev/mmcblk0p1       /media/card          auto       defaults,sync,noauto  0  0

Como puede ver, está "omitiendo por completo los metamenders" / etc / fstab y simplemente escribiendo un archivo de stock.

Respuestas

Bueno que .*@MENDER_BOOT_PART@.* en su expresión sed evaluar?

Por lo que puedo ver, no tienes nada que coincida con ninguno de .*@MENDER_BOOT_PART@.* ni.*@MENDER_DATA_PART@.* en ti fstab.

Si mi comprensión es correcta, podría usar algo similar a

 echo "data" >> ${D}${sysconfdir}/fstab
