# Set up /tmp as ramdisk
See also LinuxRamDisk.

In `/etc/fstab` add something like
```plaintext
tmpfs /tmp tmpfs defaults,noatime,nosuid,nodev,mode=1777,size=1024M 0 0
```
or
```plaintext
tmpfs /tmp tmpfs defaults,noatime,nosuid,nodev,noexec,mode=1777,size=512M 0 0
```
the `noexec` option perhaps has some uses, but can be annoying.
