Build a mini Linux from scratch (5)

Tag: Build Linux from scratch build Linux

20. Edit the/etc/fstab file to further refine the rc.sysinit and Inittab files

21. The first Test starts

22. Compile kernel use to support network function (directly compile as core)

23. Ninth Test start

24. Compile the kernel to enable it to support network functions (compile as module)

25. Tenth Test Start

20. Edit/etc/fstab, perfect Rc.sysinit, Inittab
