TMPFSAn excerpt from an article (Christoph Rohland, Nov 2001):
- Tmpfs is a file system which keeps all files in virtual memory.
- Everything is temporary in the sense that no files will be created on your hard drive. If you reboot, everything in tmpfs will be lost.
- In contrast to RAM disks, which get allocated a fixed amount of physical RAM, tmpfs grows and shrinks to accommodate the files it contains and is able to swap unneeded pages out to swap space.
