Make a little Linux of your own

Practical operation of a small Linux home

Overview: with the previous system start-up process, we have a rough idea of what files and procedures are required for Linux to boot, and now we can make a little Linux of our own.

Practice steps:

1. Add a new hard drive to existing Linux

2, partition the new hard disk, two partitions are/boot and/partition (prepared for home-made Linux)

3. Format the partition and mount it to two directories (I am here for/mnt/boot and/mnt/sysroot)

4. Install grub on this new hard drive and write the grub configuration file

5. Copy the Vmlinuz files and Initramfs files to the/mnt/boot directory

6. Create a root file system for small Linux under/mnt/sysroot

7, copy Bash and some common commands and their corresponding library files to the corresponding directory under/mnt/sysroot

8. Open a new Linux and start the test with the disk that you just started

Specific operation:

1. Add a new hard drive to existing Linux

4. Install grub on this new hard drive and write the Grub configuration file (the Grub profile can copy the native grub.conf file and change the content to the following content)

8. Open a new Linux and use just that disk as the new Linux boot drive
