Is possible rum openwrt direct from ram ? (like puppy linux)

I have raspberry pi , and have a much ram , i try found into wiki or google and no have this information  is possible inform this procedure is possible ?

Hi , is is possible, what i need ?

What do you mean "directly from RAM"? RAM is Random Access Memory.

Yes you can use an "initrd" image which includes the root filesystem as a RAM drive.

You need a way to load it into RAM though.

Yes , i not sure is included in openwrt or is possible include this function in this system , and for this cause , a request information .

In page : http://puppylinux.org/main/Overview%20a … tarted.htm have this information :

"Runs from RAM, making it unusually fast even in old PCs and in netbooks with solid state storage media."

In last years , i try puppy on ram , is more fast , and for repetitive use , is better to speedy and stability use system on ram , i would like to know if with openwrt it is possible , for example , run asterisk or router , without decrease durability sdcard on pi.

Hi , thanks your information , i search but not found information to make initrd with root filesystem , is possible informe ne how to for i read ?

You could boot from the SD card then shadow the root file system in a RAM disk.  I doubt that would make a noticeable difference in speed though.  Most router operations do not access the disk after startup.

In my case , i need run to ram , for 1 more speed , 2 sdcard have more life time 3 install softwares and after reboot , return for default factory (or last configure) .

my goal is run samba server , and asterisk , if i have problem with configuration , i reboot and have all data in last conf and more , i running on ram , I no have limitation IO sdcard .

Thanks your answer .

For you goal it is better to setup a x86/64 system for the performance.

Sorry, I understain, but my hardware for use power on is raspberry, It stays power on 24/7.

For me to configure and test, ok (x86), I have a VM with openWRT 15.05, but a procedure or an article on how to do what I am looking for, in order to learn.

Thanks your answer .

Guys, there is no sense in quoting the complete previous posting.
