My machine has lots of memory, so I moved ~/.cache/google-chrome into /tmp, which is a tmpfs RAM disk.
This makes the browser run faster and reduces SSD usage.
When I reboot, it all goes away, but it gets recreated again.
All is fine.

In theory, I could move all of ~/.cache there too.

But in practice, how likely is it that some packages (ab)use ~/.cache for something other than temporary reproducible data?

UPDATE:

I decided to try it out and did this:

$ mv ~/.cache ~/.cache.old
$ ln -s /tmp/home/ray/.cache ~/.

and then added this to my ~/.profile:

mkdir -p /tmp/home/ray/.cache

and so far everything is working okay across reboots. Removing .cache.old will free up about 2G of mostly ancient files.

If I ever do run into any packages that misuse .cache, I can teach .profile to add a symlink back to a real directory for that specific case.

  It's unfortunate, but I've already run into a couple of apps that do store preferences in ~/.cache, the most glaring being Evolution. You're probably going to have to test each app individually to see what breaks.
