Персонален битов bbapend неправилно прибавяне на файла mender fstab - linux, sed, embedded, yocto, bitbake

Използвам github.com/mendersoftware/meta-mender в моята yocto build. Искам да редактирам / etc / fstab, използвайки sed с bbappend файл в моя собствен слой. По-конкретно meta-mender понастоящем предоставя собствен файл fstab и го редактира с a base-files_3.%.bbappend, а аз просто искам да премахна auto ключова дума от генерирания / etc / fstab.

Проблемът е, че когато доставям собствената си добавка(моят слой има по-висок приоритет от мета-мендър) в моя слой за base-files_3.%. bbappend, meta-mender fstab изглежда изобщо не е създаден, а вместо това е запаса от отворено вграждане.

Ето моя мета слой / рецепти-ядро / база-файлове / база-файлове_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
}

Ако тичам bitbake -e base-files, след това потърсете функцията do_install, можете ясно да видите, че моята sed командите са правилно добавени към мета-мендер / мета-мендър-ядро / рецепти-ядро / база-файлове / база-файлове_3:

И все пак, моят / etc / fstab изглежда така:

# 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
tmpfs                /run                 tmpfs
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

Както можете да видите, той напълно пропуска мета-мендери "/ etc / fstab файл и просто пише запасен.

Отговори:

Е, какво прави .*@MENDER_BOOT_PART@.* във вашия sed-изразяване оценявате да?

Доколкото виждам, нямате нищо, съвпадащо с нито едно от тях .*@MENDER_BOOT_PART@.* нито.*@MENDER_DATA_PART@.* във вас fstab.

Ако разбирането ми е правилно, бихте могли да използвате нещо подобно на

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