LFS-RPM/README.MD

# OVERVIEW:
	This build tracks linux from scratch version 9.1

# REQUIREMENTS:
	1. git installed on the host
	2. wget on host system
	3. Directory for build, mounted at /mnt/lfs

		There will need to be a partition mounted there.
		You will be responsible for that.
		This build system uses whatever filesystem that is present at ${LFS}
	
	4. run version-check.sh and install required packages if needed

# WARNING:
	This build system is designed in such a way to not be
	able to trash your host system.  Mistakes can happen.
	I am not responsible for trashed host systems.  You
	bear all responsibilities for any failures.

# GENERAL NOTES:
	This system was designed and debugged on an AMD64 {x86_64} system
	and does not support i686.

	The build system installs/work directory:
	/mnt/lfs/usr/src/LFS-RPM

	This build has a mkinitramfs step (which requires cpio) this step
	creates an initrd so cpu updates and firmware is loaded.
	Your lfs kernel should be configured to use this.

	This build has linux-firmware to provide firmware for various
	hardware.
	See BLFS book for more information.

	I have installed rpm macro files in:
	/home/lfs/.rpmmacros
	This makes the rpm environment correct so it builds
	the base system correctly.

# ADDITIONS:
- rpm
	- the package manager
- mkinitramfs
	- to create initramfs
- cpio
	- needed for mkinitramfs
- popt
	- needed for rpm
- python2
	- needed for rpm
- wget
	- needed to fetch packages
- linux-firmware
	- needed to boot under certain hardware

# BUILD PROCEDURE:
	login as root user
	fdisk /dev/sdx				partition drive, you need to do this
	mkfs.ext4 /dev/sdxx			create ext4 filesystem
	
	install -vdm 755 /mnt/lfs		create lfs directory
	mount /dev/sdxx /mnt/lfs		mount partition to work directory
	install -vdm 755 /mnt/lfs/usr/src	create build directory
	cd /mnt/lfs/usr/src			goto build directory
	
	Now fetch the build system it will go into /mnt/lfs/usr/src/LFS-RPM by default
	git clone https://git.cromer.cl/cromer/LFS-RPM.git
	
	cd LFS-RPM				Lets do this
	./setup.sh				setup environment and fetches source tarballs
	./lfs.sh				build it
	./cleanup.sh				cleanup host
	
	Build at this point is complete.
	All that is needed is to install grub and/or add a menu item in the
	the grub configuration file /boot/grub.cfg
	
	This completes the build.

# GRUB EXAMPLES:

	GPT partitioned drive
	menuentry 'Linux From Scratch (9.1) (on /dev/sdxx)' {
		insmod part_gpt
		insmod ext2
		set root='hdx,gptx'
		linux /boot/vmlinuz-5.5.3 root=/dev/sdxx
		initrd /boot/initrd.img-5.5.3
	}

	MSDOS/BIOS partitioned drive
		menuentry 'Linux From Scratch (9.1) (on /dev/sdxx)' {
		insmod part_msdos
		insmod ext2
		set root='hdx,msdosx'
		linux /boot/vmlinuz-5.5.3 root=/dev/sdxx
		initrd /boot/initrd.img-5.5.3
	}
	Change the x's to the proper drives and partition

# INSTALLER SCRIPT:
	The installer.sh script will take the binary rpms (chapter 6) and
	install them into a partition that YOU mounted on /mnt. If you want
	to install else where then change ROOTPATH="/mnt" to the installation
	partition mounted by YOU.

# SCRIPTS:
- base.sh
	- builds chapter 6
- cleanup.sh
	- cleanup host system after build
- installer.sh
	- install rpm binaries to mounted partition
- lfs.sh
	- builds the whole thing
- setup.sh
	- configure for build
- tools.sh
	- builds chapter 5
- version-check.sh
	- checks host system for requirements
