Install ubuntu with root-on-flash
Hi,
I need to build a system with very low stand-by power requirements.
If the system is actually used I can afford higher power drain.
In order to do this I need to keep the HD off when the system is idling.
For several reasons Linux likes to read/write a lot on disk (mainly /var, but not only).
I think I have to boot unto a ram-drive, but doing so in the "stupid" way means I would lose all configurations at startup.
I thought about using an USB-pendrive to boot and I found several tutorials, but they were all meant to use an USB-stick as boot-media (instead of the normal CD) to perform normal HD installation. Nothing that would use the pen-drive for routine boot.
As said I can afford to have an HD on /usr and the delay due to spin-up on startup and start of "real" usage, but I do not want the disk to start every few minutes if nobody is at the keyboard.
Can someone advise on the best course of action?
Pointers welcome.
