The reason it doesn't work is that the network is not ready before the mount -a is executed. The client receives this and so the client downloads the network boot program. But there's a limit to the amount of bandwidth users can share on a hub-based network. Booting using these files can happen in multiple ways: Either with direct support from the machine BIOS plus network configuration (DHCP server etc). System Boot ProcessThe following diagram demonstrates the steps involved in a system boot process −Here are the Same here. If you are not on a corporate network where someone has set up a pxe server . Since Bookworm defaults to Network Manager for networking instead of dhcpcd, the way that option worked can't be used any more. If you work in an office, you probably use a LAN (local area network), which is typically a few separate computers linked to one or two printers, a scanner, and maybe a single, shared connection to the Internet. an operating system image and 3. Pressing the Pause/ScrollLock button on the keyboard early in the boot (before PXE starts it's boot atempt) can achieve the same thing.
