What am I missing? > If you created your stage 1 script with s6-linux-init-maker, and you see nothing in your stage 1 that mounts /dev, it means that you told s6-linux-init-maker that your kernel automounts /dev at boot time. So, your /dev is already mounted when the kernel spawns init. The kernel option triggering that behaviour is named CONFIG_DEVTMPFS_MOUNT. Thanks Laurent! I'm sure that's how it's set up, and I just forgot I'd enabled that configuration setting. Cheers, Brett
