I use Arch (btw). It comes with tmpfs that's a userspace physical memory mounted as a temporary file system which is miles faster even compared to a typical NVME.
Question is, I do have my
~/.cache linked to
/tmp so whatever writes happen as cache will be temporary to one session.
I don't have any trackers, file system indices or any important cache specific data (other than clipboard yanks being removed upon each reboot, which indeed considered a safety mechanism).
Do anyone even consider this cache workflow? If so, why?
