从log上看/dev/block/platform/fe2e0000.mmc/by-name/userdata不存在，可以通过access("/dev/block/platform/fe2e0000.mmc/by-name/userdata", F_OK)判断是否存在，还可以通过添加以下代码先把shell打开，然后查看信息
execv("/bin/sh", NULL);

我之前调init时遇到问题总结的

回复 润开鸿_闻飞: ramdisk里也有一个init，这个与system里的init有什么区别？我开着enable_ramdisk了，把ramdisk.img也打到boot_linux分区了。我现在没搞明白，ramdisk里的init和system的init是一个init吗。我感觉ramdisk的编译依赖不合适，如果要enable_ramdisk打到boot_linux.img里，那就要ramdisk.img先被编译。怎么单独编译ramdisk.img？

回复 闲散鸿-Zdd: 你是哪个分支？OpenHarmony-4.1-Release分支及以后才有，如果没有的话那就是base/startup/init/services/init/main.c文件的流程往下走然后在base/startup/init/services/init/standard/init.c的StartInitSecondStage函数中加execv("/bin/sh", NULL);
