自定义bitbake bbapend没有正确附加mender fstab文件

标签： linux sed embedded yocto bitbake

我在yocto构建中使用github.com/mendersoftware/meta-mender。我想使用sed在我自己的图层中使用bbappend文件编辑/ etc / fstab。具体来说，meta-mender目前正在提供他们自己的fstab文件并使用base-files_3.%.bbappend进行编辑，我只想从生成的/ etc / fstab中删除auto关键字。

问题在于，当我在我的图层中为base-files_3。％。bbappend提供我自己的bbappend（我的图层具有比meta-mender更高的优先级）时，meta-mender fstab似乎不是根本就是创建的，而来自open-embedded的库存则是。

这是我的元层/ 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
}

如果我运行bitbake -e base-files，然后查找do_install函数，您可以清楚地看到我的sed命令正确地附加到meta-mender / meta-mender-core / recipes-core /碱基文件/基层 - files_3：

然而，我的/ etc / fstab看起来像这样：

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

/dev/root            /                    auto       defaults              1  1
proc                 /proc                proc       defaults              0  0
devpts               /dev/pts             devpts     mode=0620,gid=5       0  0

mode=0755,nodev,nosuid,strictatime 0  0
tmpfs                /var/volatile        tmpfs      defaults              0  0

# uncomment this if your device has a SD/MMC/Transflash slot
#/dev/mmcblk0p1       /media/card          auto       defaults,sync,noauto  0  0

正如您所看到的，它完全跳过了元商人和＃39; / etc / fstab文件，只写一个库存。

答案 0 :(得分：1)

那么，你的sed-expression中的.*@MENDER_BOOT_PART@.*评估为什么？

据我所知，你fstab中的.*@MENDER_BOOT_PART@.*和.*@MENDER_DATA_PART@.*都不匹配。

如果我的理解是正确的，你可以使用与

类似的东西 
 echo "data" >> ${D}${sysconfdir}/fstab
