参考的大神的帖子
runadaemon
我在一年多以前也发帖问过，但是别的问题，后边因为项目原因没有继续研究下去。我的帖子
手机版本：iPhone4s,8.1.3
MAC版本：10.12.3
theos安装路径：~/theos
按照大神的帖子一步步的做下来，Makefile,control文件都是默认的。从修改plist文件，修改main.mm文件，创建layout目录，下载fauxsu并且修改权限和用户组为 root/wheel，以上步骤和帖子里情况都是一样的。
将deb安装到手机上，在xcode上没有查看到日志。
因为我的手机系统图标都不见了，cydia也不能启动，其他插件暂时还无法安装。
帮忙看看deb权限的问题吧
权限问题已经解决
权限问题。在这篇帖子的回复里查看@LiserYu的回复
问题已经解决！原因是在El Capitan之后，mac 系统文件修改权限加入了系统完整性保护（System Integrity Protection，其目的是为了阻止系统文件，包括auvaltool，被修改，这是在El Capitan之后才有的一个新特性）所以需要先关闭这个功能之后，执行上面的 sudo chmod 语句才会有效，具体关闭方式是
重启电脑 并按住Command＋R，进入recovery分区，之后从菜单栏中选择工具(Utilities)->终端(Terminal)，之后在终端中输入csrutil disable; reboot 再回车即可。
使用这种方法已经能够修改deb的权限。安装后查看目录
/usr/bin 目录下存在 rootdaemond
/Library/LaunchDaemons 目录下存在 com.iosre.rootdaemond.plist
另外因为我的手机系统app都没有入口了，所以安装不了ps syslog等工具。我就修改了下main文件,添加了一个定时打印日志的循环
int main(int argc, char **argv, char **envp)
{
NSLog(@"iOSRE: rootdaemond is launched!");
system("iOSRE: rootdaemond is launched!");
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
while (YES) {
[NSThread sleepForTimeInterval:5];
NSLog(@"rootdaemon begin to run");
}
});
CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(), NULL, Reboot, CFSTR("com.iosre.rootdaemon.reboot"), NULL, CFNotificationSuspensionBehaviorCoalesce);
CFRunLoopRun(); // keep it running in background
return 0;
}
重启手机后。数据线连接手机查看日志。日志如下

根据日志来看，代码里的日志都没有出现，但是却有很多com.iosre.rootdaemond进程的错误日志。而且还会定时打印日志。是不是daemon已经在运行了。
错误日志搜了下也没看出个所以然，
有没有遇到相同情况的
