Mount a temporary ram partition

Makes a partition in ram which is useful if you need a temporary working space as read/write access is fast.

Be aware that anything saved in this partition will be gone after your computer is turned off.

Know a better way?

If you can do better, submit your command here.

What others think

many systems come with a shared-memory "Device" pre-mounted. My distro (fedora) is mounted at /dev/shm.

Pretty handy when you want to borrow some ram for disk like purposes.

this is really great if you run gentoo and are going to compile something - if you mount a tmpfs at /var/tmp/portage, it'll emerge while storing temp files in ram instead of on the harddrive, leading to a faster emerge that doesn't bog down your harddrive. Take note though, not everything will compile if you don't have enough ram, esp. if it's something like gcc or gtk... about 700mb should be fine (i think)

this might be of interest too:

No doubt this would torn out the ram while doing heavy-duty work provided if mounted under restricted places ;)
