Description
a loader is just a program that
- parses config/binary formats
- loads data to memory
- uses kexec and reboot syscalls
u-root already has lots of parsers, and different OS kernels have different expectations from the loader, e.g. initial page table setup (FreeBSD, Haiku).
Clarify how instead of chaining a standalone binary a loader is implemented as a Linux userland program for LinuxBoot.
We may want to hint on loading other Linux programs from external sources instead of just kernels.

Research direction
Start with the book's existing loader guidance and the u-root context described in the issue. Explain how a LinuxBoot loader works as a Linux userland program, covering config and binary parsing, loading data into memory, and kexec and reboot syscalls. Also address OS-specific expectations and whether to mention loading other Linux programs from external sources; done when the guidance clearly covers these decisions.
