So I'm poking at a vfork() based xvdaemon() with nommu support, and the ONLY caller of daemon() without 0,0 arguments is watchdog. I think not closing stdin/stdout/stderr is irrelevant here (it doesn't use them afterwards? Do you WANT it to stay attached to the tty in -F mode?), but the no chroot("/") is my question: Do you want to support relative DEV arguments in the watchdog command? Because if not, I can just make xvdaemon() take no arguments and unconditionally do both, which is what every other caller wants so far. (The error handling is a pain, because we closed stdin/stdout/stderr so HOW do we report errors afterwards... open /dev/tty I guess... but the other thing is the vfork() flow control requires restarting from command_main() each time so the caller of xvdaemon() has to be aware of this. The command restarts when it's called, but the second call returns rather than restarting. So I have to audit each caller while converting, and remove some of the depends on TOYBOX_FORK annotations from the commands...)
