In some distros/setups, /tmp is actually RAM - i.e., when you write to it, no actual disk write occurs.
Does Raspbian work that way, or does writing to it actually write to the SD card?
(The underlying point here, of course, is that I'd like to not be writing to the SD card if I can avoid it, for temporary files. Note that I can also setup a regular ramdisk (using /dev/ram0) - and that works - but I'm curious if /tmp would accomplish the same thing.)
P.S. Note that one side effect is that if /tmp is actually RAM, then there is no need to cleanup /tmp as part of the bootup sequence.
