Making partitions questions.

Hi Alexandr!

The reason why this have to be done is that the mtd partition driver needs
to know the partition information before it can register those partitions as
devices (it basically just goes and setup MTD structures for each partition
and register them the normal way).

In order to actually make a userland utility you'd have to implement a
system call to actually send the info to the partition driver which will
have to reregister the devices. Not all that difficult, but I don't think
anybody is working on it right now.

Yes. As long as you compile your kernel with MTD block device support it,
you can put anything on those block devices. I wouldn't use ext2 on flash
tho since it's not optimised for flash - jffs2 is definitely your best bet.
