Its only +purpose is to provide an initial /dev/console to the kernel +when it starts process 1. +The directory should contain a working /dev/console device! + + init-stage1 will close all handles to this /dev/console, +then mount the tmpfs and copy the tmpfs image to the tmpfs +- the image contains a full version of /dev, which will then +be used. + This trick is necessary to have a working read-write /dev +when you have a root-only filesystem and when you cannot or +do not want to rely on fancy Linux-specific tricks such as +devtmpfs. |
