Build a simple bootable Linux based on the host

1. Create a new system root directory/mnt/sysroot:

   #mkdir/mnt/sysroot

   
   

2. Add a piece of hard disk/DEV/SDB to format the target disk partition

Two:

On host:/DEV/SDB1,/DEV/SDB2

/DEV/SDB1 Mount to/mnt/sysroot/boot(target host root file system creation complete and then mount)

/DEV/SDB2 Mount to/mnt/sysroot

Create a root file system for the destination host

# mkdir-pv/mnt/sysroot/{etc/rc.d, USR, var, proc, Sys, Dev, lib, lib64, Bin, sbin, boot, SRV, mnt, media, home, Root

Then through the bincp.sh script to transplant Bash and other to the target host root file system:

The contents of the bincp.sh script are as follows:

3. Install GRUB to target disk

# Grub-install--root-directory=/mnt/sysroot/dev/sdb

4. Copy kernel and INITRD files

# Cp/boot/vmlinuz-version/mnt/sysroot/boot/vmlinuz

# cp/boot/initramfs-version.img/mnt/sysroot/boot/initramfs.img

5. Provide configuration files for grub

# vim/mnt/boot/grub/grub.conf

Default=0

Timeout=5
