Niestandardowy bitbake nie dołącza poprawnie pliku fstab do mendera - linux, sed, embedded, yocto, bitbake

Używam github.com/mendersoftware/meta-mender w mojej kompilacji yocto. Chcę edytować / etc / fstab używając sed z plikiem bbappend w mojej warstwie. W szczególności, meta-mender obecnie dostarcza własny plik fstab i edytuje go za pomocą base-files_3.%.bbappendi chcę tylko usunąć auto słowo kluczowe z wygenerowanego pliku / etc / fstab.

Problem polega na tym, że kiedy dostarczam własny bbappend(moja warstwa ma wyższy priorytet niż meta-mender) w mojej warstwie dla base-files_3.%. bbappend, meta-mender fstab nie wydaje się być w ogóle tworzony, a zapasowy z otwartego osadzenia jest zamiast tego.

Oto moja meta-warstwa / core-files / 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
}

Jeśli biegnę bitbake -e base-files, poszukaj funkcji do_install, możesz wyraźnie zobaczyć, że moja sed komendy są poprawnie dołączane do meta-mender / meta-mender-core / recipes-core / base-files / base-files_3:

A jednak mój / etc / fstab wygląda tak:

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

/dev/root            /                    auto       defaults              1  1

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

Jak widzisz, „całkowicie pomija plik meta-menders” / etc / fstab i po prostu pisze zapasowy.

Odpowiedzi:

No cóż .*@MENDER_BOOT_PART@.* w twojej ekspresji sed oceniać?

O ile widzę, nie masz nic pasującego do żadnego z nich .*@MENDER_BOOT_PART@.* ani.*@MENDER_DATA_PART@.* w tobie fstab.

Jeśli moje zrozumienie jest poprawne, możesz użyć czegoś podobnego do

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