But with only 1 GB capacity

• glandium 9y ago
  It depends on your setup. The default when no size is given is to use half the RAM.

    Half? That seems kind of excessive. Are you sure that’s right?
    • Sidnicious 9y ago
      I would guess that it’s given that capacity, but the memory is allocated lazily.

        Correct; tmpfs only uses as much memory as as is used by the files it contains.
