Comment on Is it possible to install a distro directly from online ?

Technically there would be network booting. I think it was intended to work over the local network but I don’t see why TFTP wouldn’t work over the Internet (when skimming the Wikipedia article). But be warned, TFTP (and thus netboot) has no security features, so you could receive a manipulated PXE (pre boot execution environment).

  That is not the kind of Network boot I meant, they ride on the name for the standard IMHO

TFTP is fine for LAN, but very inefficient for sending bulk data over the Internet.

To keep things as simple as possible, TFTP sends one packet at a time, waiting for a response before sending the next packet. If your ping is 50 ms, the that’s 20 whole packets per second. (That’s assuming zero packet loss, otherwise it will be even slower.)

For historical reasons, the packet size is locked to 512 useful bytes. That puts the transfer speed at 20 kB/s (160 kbps), which is faster than dialup but not by much.
