Mount Partition

Execute the following command to create a path to mount partition, and mount the partition under that path:

$ mkdir mount_path

The 3rd path (/boot path):
```
$ sudo mount /dev/sdb3 mount_path
```
The following is the example output:
Figure 1. Example Output

Result: After mounting, files in the /boot path of the Debian system can be viewed in this path.
Execute the following command to unmount partition:
```
$ sudo umount /deb/sdb3
```
The 4th path (/ path):
```
$ sudo mount /dev/sdb4 mount_path
```
The following is the example output:
Figure 2. Example Output
Execute the following command to unmount partition:
```
$ sudo umount /deb/sdb4
```
Note: In embedded Linux systems, the /boot directory is usually used to store boot related files, such as boot loaders and kernel images, while the root directory / contains other files and directories of the system. The /boot directory and root directory / are usually divided into different partitions.
- When the /boot directory is in an independent partition, there is also a /boot directory in the root directory /.
- When the /boot partition is mounted to the root directory /, the /boot directory under the original root directory / will be hidden, and the content of the /boot partition will be exposed under the /boot path of the root directory /.
This approach separates bootloader and kernel image bootloader from the root file system. This can improve the security and stability of the system. However, it is necessary to avoid writing files in the /boot path of the root directory /, otherwise conflicts may arise when mounting on the /boot partition.
