alt Hacker NewsThe writing is really succinct and easy to follow.
One thing that could be improved is that the author could break down some of the commands, and explain what their arguments mean. For example:
> mknod rootfs/dev/console c 5 1
Depending on the reader's background, the args 'c', '5', and '1' can look arbitrary and not mean much. Of course, we can just look those up, and it doesn't make the article worse.
For anyone curious: "c" just means that it's a character device.
There is also "b" for block device (e.g. a disk, a partition, or even something like a loopback device) and "p" for FIFOs (similar to mkfifo).
The two numbers are just identifiers to specify the device, so in case of `5 1` it means the systems tty console, while `1 8` would mean "blocking random byte device" (mknod dev/random c 1 8)
