Summary: Moving /tmp to tmpfs makes it useless

That is linked from
https://wiki.debian.org/SSDOptimization/#Reduction_of_SSD_write_frequency_via_RAMDISK
What I didn't like from the post is that it doesn't clearly
state the downsides.
Particular user may run applications requiring more space in /tmp than
is configured by default for RAM disk. Examples are image manipulation,
processing scientific data. The thread contains links to earlier
discussions. I admit that I have more free RAM + buffers than free space
on / as well, but it is a conscious choice.
That is a link that I had. I do not have another one with a better
balanced opinion. My point that the suggestion may lead beginners to
trouble, so they should be warned.
Notice that debian wiki recommends tmp.mount systemd unit instead of
/etc/fstab line. Unsure if provides more flexibility or other advantages.
P.S. Arbitrary time may be invested in optimization attempts. There are
interesting features like swap in RAM (compressed memory pages). Some
people get better performance for tasks like compiling chrome. Some can
not achieve it.
