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.
