From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

No, but it becomes invisible and inaccessible* as long as the filesystem is mounted over it - see this Stack Exchange question and accepted answer.
The benefits are marginal, for example I can see if a filesystem is mounted by simply typing
ll /mnt
(ll
being an alias ofls -lA
) - it comes handy with my system due to how I manage a bunch of virtual machines and their virtual disks, and it's short and easy to type.Some programs may refuse to write inside inaccessible directories, even if the root user can always modify regular files and directories as long as the filesystem supports it.
It's not a matter of security, it's more of a hint that if I'm trying to create something inside those directories then I'm doing something wrong (like forgetting to mount a filesystem) and "permission denied" errors let me know that I am.
Now I understand.
This is all new to me bro.
Even I don't know if I will go this further to explain something to someone.
Thanks Chad.
