Thats not true (and I've used tmpfs for tmp for years, so I'm speaking
from experience)— tmpfs is backed by swap on demand. Just add the
space that you would have used for /tmp to your swap.
Wait a minute. Back in this thread it says that half of RAM is allocated to the tmpfs for
/tmp.
Plus the purported benefit from this is causing less write cycles on SSD. (See Wiki
page)
That may have been a benefit a few years ago but newer SSD's will gain almost nothing
from this because of the enormous
number of write cycles they handle.
This "feature" may have some benefits but I think they are infinitesimally
small.
