I am working on making Linux (FC2) run on a flash disk.
Cool project... but you will need a 512MB minimum I would think.
To avoid the write-cycle limits on the flash it must be configured
without
a swap drive and remove any extraneous logging. I have eliminated the swap
partition, however I am not sure what logs are created and how to eliminate
them or direct them to /dev/nul. The objective is not to beat the flash to
death since there is a 1 million write cycle limit.
The one way I know would work is to create a small ramdisk during init and use
mount --bind to mount it over /var/log
I am also trying to make the kernel static, w/o modules, to keep the
speed
up as the flash is slow. Here my attempts have been less that acceptable. I
constantly get errors on the build and can't seem to eliminate all the
modules.
Are you sure that loading a few modules is going to make the slightest bit of
noticeable difference?
Finally, to use some sort of sleep mode to avoid the re-boot delay on
the
re-application of power. Once developed the system will not ever see any
different configuration. Here I can't find much information on how to do
this.
ACPI handles this on modern systems, but it is really cranky about which BIOS
you have.
Any pointers on any of these subjects will be greatly appreciated. If
not
already done, I will gladly post a HOW-TO when done.
