    This is absolutely true if /tmp is mounted on tmpfs, which is left
to amin's choice. /tmp is typically used by Thunderbird to store
attached files, maybe also by other applications I admit Thunderbird is
maybe not a use case for Pi. Anyway RAM might be short to store such
files. Also, nowadays /tmp is cleared on reboot only if it is mounted on
tmpfs, otherwise you should manage it yourself but you can prefer let it
survive.

    If the admin decides to put /tmp on mmcblk0, then there is still
/run to store very small files. Since /run exists anyway, why not make
it available to the user? There is no cost in doing that.
