Linux is awesome! And one thing of its awesomeness is that we create
virtual drives in RAM, very easy! With only one command we can create a
drive in RAM and store temp files, for various reasons.
The main reasons is speed and protection of the disk drive or SD Card. In
Raspberry Pies, both reasons are very important, as the SD-Card of an rpi
is slow and don't allow too many read/write operations. So enough talking.
The easy way in one command:
sudo mkdir -p /vram/ && sudo mount -t tmpfs -o size=100m tmpfs /vram
Because its only one command (acctually two), we can use it in scripts and
by demand only. When we need it, we create it. But if you want a permanent
solution, try this:
#> sudo mkdir /var/tmp
then edit the fstab file by:
#> sudo nano /etc/fstab
and add the line:
tmpfs /var/tmp tmpfs nodev,nosuid,size=1M 0 0
save and close the file. Now issue:
#> sudo mount -a
This way, even when you reboot the ram disk will be created automatically.
Beware that in shutdown/reboot, a ram disk is being emptied. So, don't
write data, that you need.
