How to setup tmpfs(ramdisk?) to protect SD card?

[hune6imo]

Please teach me how to set up tmpfs to protect SD card from heavy writes.

I want to use RAM disk for:
/tmp/*
/var/log/*

I want RPi to save files to ram disk, not a SD card.

~# help?

Specify it in /etc/fstab?

You don't need to install anything.

Look at the link given. It even shows you an example of using tmpfs for /tmp.

Add the following to /etc/fstab:-
sudo nano /etc/fstab

Code: Select all

tmpfs /tmp  tmpfs defaults,noatime 0 0
tmpfs /var/log  tmpfs defaults,noatime,size=16m 0 0
