OVERVIEW:
|
||||
This build tracks linux from scratch version 8.4
|
||||
#-----------------------------------------------------------------------------
|
||||
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 partition mounted there.
|
||||
You will be responsible for that.
|
||||
This build system uses whatever filesystem
|
||||
that is 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.
|
||||
Not responsible for trashed host system. You
|
||||
bear all responsibilities for any failures.
|
||||
#-----------------------------------------------------------------------------
|
||||
GENERAL NOTES:
|
||||
This system was designed and debugged on an AMD64 {x86_64} system
|
||||
and I have not tested it on a i686 system as I no longer have or
|
||||
use such systems.
|
||||
|
||||
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 Microcode updates for AMD CPUs.
|
||||
To use it make a link to the proper cpu family.
|
||||
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:
|
||||
cpio # needed for mkinitramfs
|
||||
mkinitramfs # to create initrd
|
||||
popt # needed for rpm
|
||||
python2 # needed for rpm
|
||||
rpm # package manager
|
||||
wget # needed to fetch packages
|
||||
firmware-radeon # firmware for radeon graphics
|
||||
firmware-realtek # firmware for realtek network
|
||||
firmware-amd-ucode # microcode updates for AMD CPUs
|
||||
#-----------------------------------------------------------------------------
|
||||
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://github.com/baho-utot/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:
|
||||
|
||||
GPT partitioned drive
|
||||
menuentry 'Linux From Scratch (8.4) (on /dev/sdxx)' {
|
||||
insmod part_gpt
|
||||
insmod ext2
|
||||
set root='hdx,gptx'
|
||||
linux /boot/vmlinuz-4.20.12 root=/dev/sdxx
|
||||
initrd /boot/initrd.img-4.20.12
|
||||
}
|
||||
|
||||
MSDOS/BIOS partitioned drive
|
||||
menuentry 'Linux From Scratch (8.4) (on /dev/sdxx)' {
|
||||
insmod part_msdos
|
||||
insmod ext2
|
||||
set root='hdx,msdosx'
|
||||
linux /boot/vmlinuz-4.20.12 root=/dev/sdxx
|
||||
initrd /boot/initrd.img-4.20.12
|
||||
}
|
||||
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
