Use tmpfs more widely

[GordianLN]

The sd image, and also in general system safety, would benefit from setting up a small tmpfs mountpoint (let's say 200MB tops) for /tmp, maybe /var/log (would need aggressive rotate settings), and /var/tmp

[openoms]

does a separate tmpfs has any advantage over /dev/shm created automatically and used already for sensitive files?

[GordianLN]

IMHO, it allows any process to use tmpfs for temporary files, even those which do not specifically target /dev/shm, yet I'm probably giving it too much importance
