In the Linux system, the "opt" directory is not mounted on other directories, but is located directly under the root directory "/", which means that it exists as part of the root file system, unlike other The directories are at the same level. In different Linux distributions, the directory structure may be different, so please confirm according to the specific environment.

In Linux systems, the "opt" directory is usually used to install optional third-party software packages and applications. It is a conventional directory used to store non-operating system core software.
Normally, the "opt" directory is not mounted on another directory, but is located directly under the root directory ("/"). This means that it exists as part of the root file system, at the same level as other directories (such as "/bin", "/etc", etc.).
For example, the full path may be "/opt". You can use the following command to view the directory list under the root directory:
ls /
If you cannot find the "opt" directory under the root directory, it means that the directory may not exist or has been moved to another location. The directory structure may vary between Linux distributions, so please confirm with your specific environment.
