tmpfs will swap.

  > tmpfs will swap. We are both wrong to a degree, but you are more correct than I was. According to the docs[0]: tmpfs ... is able to swap unneeded pages out to swap space, if swap was enabled for the tmpfs mount. So `tmpfs` does not unconditionally use swap, but can use it if possible. What I was thinking about is `ramfs`, which doesn't support swap, but that is not the topic of the question to which I replied. 0 - https://www.kernel.org/doc/html/latest/filesystems/tmpfs.html https://www.kernel.org/doc/html/latest/filesystems/tmpfs.htm...

    You have to explicitly disable swap. Honestly had no idea that was an option because I've never seen it disabled anywhere before.

        No like there's a tmpfs mount flag to not allow swapping.
