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.

Not OP, but speaking as a Linux newb, what is a "userspace" exactly?
Anything done locally that only affects your user is userspace. Doing configuration changes in userspace versus globally will reduce the likelihood of you breaking something. So making changes in ~/.local, for example, instead of /usr/local.
That seems to be a common usage of the term, but strictly speaking, "userspace" is anything that's not the kernel. This includes system-level programs, libraries and settings configured as "root" that can affect all users.
So is this a matter of personal profiles? Userspace would be anything within a particular user's space, if you will?
Affected your user and not the system as a whole, yes.
If you want to be a hyper technical dick like the other person responded, the old way to refer to the term "userspace" is basically anything that doesn't affect the kernel, HOWEVER, it is now more commonly used to refer to specific local user settings, yes. The old reference was way before people starting writing things to be hyper-local to individual users, as things are arranged now.
Thank you for explaining!
