Hello,
Can I use jffs2 on a ramdisk? Is jffs2 only designed to be used on flash memory devices rather than RAM devices?
What about cramfs?
TIA.
Lei

jffs2 needs an MTD device, so it can be run on any medium that MTD
supports. There are some MTD drivers for RAM based devices.
The MTD mailing list might be able to help you more
(linux-mtd@lists.infradea.org).

Your jffs2 question was already answered.
But this one wasn't answered:
> What about cramfs?
You can in fact use cramfs "on a ramdisk", e.g.:
cat image.cramfs > /dev/ram1
mkdir /mnt/cramfs
mount -oro /dev/ram1 /mnt/cramfs
mount | grep ram1
/dev/ram1 on /mnt/cramfs type cramfs (ro)
Of course cramfs also works on other block devices as well, e.g. mtdblock.

Thanks! I'll try that.
