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.

My strategy has always been to separate what should be persistent from what shouldn't be.
On every system I deploy for home or work, I have a tree similar to below
/storage/[local/remote]/[where it is, enclosure, backplane,etc]/[what it is]
E.g
/storage/local/e1/raid/r6a/[this is my mount point] /storage/remote/nfs4/oldserver/[this is my mount point]
I then build all of my workflows off of the assumptions that things go there. Docker containers have a subdirectory in r6a for persistent volumes, etc
Even my containers themselves have a /storage/remote/persistent that I symlink anything to that I care about.
On the desktop side, I tend to physically just mount a second drive or a second partition as a subdirectory of /storage. That way my assumption can always be safe in that if it's a subdirectory of a mount, my data is safe. If it's not, it isn't. It's also nonstandard, so I can be relatively certain I won't have conflicts between different distributions.
The main issue I have with submounting system directories like /home is that applications tend to put junk there, and old junk might not be compatible with a newer version of, or different distro. It can make for more effort than it's worth
