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.

A screenshot of a file manager preview window for my ~/.cache folder, which takes up 164.3 GiB and has 246,049 files and 15,126 folders. The folder was first created about 1.75 years ago with my system

/usr/local/sbin/adduser.local

One line in there and you can make it add a new line with appropriate /home/userX/.cache tmpfs line to fstab.

Or, maybe a cleaner way, you might make a init/systemd service that, when booting, would run something like

for each dir in /home do
mount dir/.tmp -type tmpfs
done

I'm not at the computer now and I'm lazy to Google it, so this above is just a pseudo code and probably won't run.

Neat, thanks for sharing

Here's the above pseudocode in bash:

find /home/ -mindepth 1 -maxdepth 1 -type d -exec mount none {}/.cache/ -t tmpfs -o size=16G \;

for doesn't work here because it uses spaces to delimit strings, which could cause issues with filenames that contain spaces

You can also create a systemd user service, which is useful if you don't have root access. The above mount command requires root, but the following doesn't and is more robust than symlinking to /tmp/:

ln -s $(mktemp -dp /var/tmp/) ~/.config/
