I also have /tmp on tmpfs, /var/tmp on disk, works perfectly fine here.

I kindof prefer each user to have their own TMPDIR, you can do that by
having this in /etc/profile, while not perfect in every regard, it
works fine here:

if [ "$UID" != 0 ]
then
  TMPDIR=$HOME/tmp
  export TMPDIR
  if [ ! -d $TMPDIR ]
  then
    /bin/rm -f $TMPDIR
    /bin/mkdir $TMPDIR
  fi
fi

RAM = random access memory, which I guess SSDs kindof are.

Perhaps, but swapping floppies was terrible and the choise to use scsi
instead of ide made the disk alternative expensive.
Below the surface there was e.g. copper lists, I don't call that user
friendly much but a lot of users played with it.

Don't remember much of the amiga, what was it that was user friendly
underneath ?
