This is a Vagrant building process for Linux From Scratch.
Before the tour of lfs building, you need install VirtualBox and Vagrant on your PC.
Clone or download this repository and change to the repository folder in the command line.
$ git clone https://github.com/Yibo-Li/linuxfromscratch.git
Cloning into 'linuxfromscratch'...
...
$ cd linuxfromscratch && ls .
LFS-BOOK-8.1.pdf lfs-config.sh* README.md sources/ Vagrantfile
lfs-build.sh* lfs-prepare.sh* script/ vagrant.sh* version-check.sh*Run vagrant up to start and provision the vagrant environment using ubuntu/xenial64. The process may spend a long time around decade minutes, because of downloading the os image and essential software.
$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Importing base box 'ubuntu/xenial64'...
==> default: Matching MAC address for NAT networking...
==> default: Checking if box 'ubuntu/xenial64' is up to date...
==> default: Setting the name of the VM: lfs
==> default: Clearing any previously set network interfaces...
==> default: Preparing network interfaces based on configuration...
default: Adapter 1: nat
==> default: Forwarding ports...
default: 22 (guest) => 2222 (host) (adapter 1)
==> default: Running 'pre-boot' VM customizations...
==> default: Booting VM...
...When the vagrant environment is ready, log in as lfs and open a tmux session to prevent terminal close unexpectedly.
$ vagrant ssh -- -l lfs

lfs@ubuntu-xenial:~$ tmux new -s work
...Test the environment variables $LFS and $LFS_TGT are /mnt/lfs and x86_64-lfs-linux-gnu, respectively. Besides the mount result is same as bellow.
lfs@ubuntu-xenial:~$ echo $LFS
/mnt/lfs
lfs@ubuntu-xenial:~$ echo $LFS_TGT

...After hours of building shut down the vagrant environment and there is a virtual disk named lfs.vdi, which contains the lfs root and swap partitions.
lfs@ubuntu-xenial:~$ sudo shutdown -h now
...
$ ls .

LFS-BOOK-8.1.pdf lfs-config.sh* README.md sources/ vagrant.sh* version-check.sh*Finally, create a new virtual box computer using the lfs.vdi virtual disk file.
And power on this new computer to log in the lfs system as root with an empty password.
In short, all above steps can be done with the three commands quickly.
vagrant up
vagrant ssh -- -l lfs 'sh /vagrant/one-click.sh'
