我想設置自定義的初始化腳本在啓動時yocto圖像中的跑,我也跟着correct answer here啓動 - 這是相同的,因爲我想 - 因爲我使用煙火版本我設置在local.conf檔案這些變量如文檔中所述與systemd運行啓動腳本在與yocto
DISTRO_FEATURES_append = 「systemd」
VIRTUAL-RUNTIME_init_manager = 「systemd」
DISTRO_FEATURES_BACKFILL_CONSIDERED = 「sysvinit的」
虛擬RUNTIME_initscripts =「」
的問題是,initscript.service不叫系統啓動的時候,我不覺得在/ var事/儘管腳本log/messages中和服務文件被傳輸並且systemd存在。
我也嘗試使用這個選項作爲替代的init在yocto
pkg_postinst_keyfile() { #where keyfile is a recipe is added to IMAGE_INSTALL_append
if [ x"$D" = "x" ]; then
logger "key file is added"
else
exit 1
fi
}
再次,我無法找到的聲明中日誌「密鑰文件補充說:」儘管配方被執行,一密鑰文件將按照預期從配方傳輸到映像。
那麼,是什麼錯了正確的答案?我看到它不錯,但我不知道問題出在哪裏。如果任何人都可以給我一個使用Vinit做等效的實例嗎?

食譜
我有一個被稱爲元mylayer層,它的樹是:
CONF/layer.conf
食譜核心/ mylayer-initscript /(如上述鏈接中所述)
個食譜核心/圖片/ apt-image.bb
的的apt-圖像是我上面核心最小的,其內容
SUMMARY = "An image which add the support of using deb package management"
inherit core-image
include recipescore/images/core-image-minimal.bb
IMAGE_FEATURES += "package-management"
IMAGE_INSTALL_append = "gnupg coreutils keyfile initscript"
IMAGE_LINGUA = " "
LICENSE = "MIT"
IMAGE_ROOTFS_SIZE ?= "16192"
PACKAGE_FEED_URIS = "http://<public ip here>/my-repo/yahia-repo/expiremental \"
PACKAGE_FEED_BASE_PATHS = "deb"
PACKAGE_FEED_ARCHS = "all"
pkg_postinst_keyfile() {
if [ x"$D" = "x" ]; then
logger "key file is added"
else
exit 1
fi
}
啓動腳本食譜內置圖像和所有文件是跟沒有改變的鏈接規定相同。
,如果你有興趣有關密鑰文件的食譜,這裏是它

服務腳本
[Unit]
Description=start initscript upon first boot
[Service]
Type=simple
ExecStart=/bin/sh -c 'sleep 5 ; /usr/sbin/initscript.sh'
初始化腳本。^ h
#!/bin/sh
logger "starting initscript"
# do some work here. Mount rootfs as rw if needed.
logger "initscript work done"
echo "hi yahia" > /deb_key/hello
我不知道這根文件系統yocto的結果是,只有R默認值或RW?

你能分享你的食譜嗎? – jku
您尚未顯示實際安裝服務文件(我瞭解問題在哪裏)的配方或服務文件本身。至於替代方法,我不確定postinst是否要在圖像配方中工作,通常它是在生成postinst函數所用包的配方中定義的。 – jku
@jku好的,我把它們 –
