What is Dev root?

/dev/root is a generic device which can be used in the fstab. One can also use ‘rootfs’. /dev/root is a virtual device like ‘proc’ or /dev/tcp’. There is no device node in /dev for these things -it’s already in the kernel as a virtual device. This explains why a symbolic link does not necessarily exist.

What is the difference between DF and Lsblk?

lsblk lists all mass storage devices and partitions on them, including mounted file systems, unmounted file systems and devices without any file system. df ‘reports file system disk space usage’, which means that it lists mounted file systems and also file systems in RAM.

What shows are on Lsblk?

lsblk: Use lsblk command to view your available disk devices and their mount points (if applicable) to help you determine the correct device name to use. The output of lsblk removes the /dev/ prefix from full device paths. It tells you the size of volume and partition(which in your case both 10 GB).
