log: Allow runtime selection of 'debug' log level
Currently, we need to compile with -DDEBUG to implement debug-level logging in the UIs and discover server. Since we may not be able to easily replace a system's petitboot binaries, this change introduces a -v|--verbose option to the discver server and ncurses UI, which enables debug at runtime. We also move some of the udev debug code out of an #ifdef DEBUG block. Since petitboot is generally started on boot, we also add a little infrastructure to pass -v to petitboot on certain system contitions: either petitboot.debug on the kernel command line, or a petitboot,debug? NVRAM property containing the value 'true'. Signed-off-by: Jeremy Kerr <>
