Gilad,

Not out of the woods yet.

I can’t just burn a tar ball straight into a raw mtd partition. When I’ll try to untar it, if I’ll do:

tar zxf /dev/mtd6

tar will read the whole mtd partition, and I don’t think it’s a good idea to use a raw device as tar file.

So should I package the tar in a filesystem, like cramfs?

That's certainly possible - just make sure your tar file is smaller then the 256Mb file limit of cramfs (if memory serves me right) - otherwise just use squashfs.


I'll add that if you're already going to have a file system (and your reasons seems to make sense to me) I would have just forgot about the tar file and put the file in cramfs/squashfs to begin with and just copy them over the initramfs during boot (something like cp -a /mnt/mtd6/* /).

In that case, I don’t need to compress the tar file, as cramfs is compressed, right?

That is correct.
