Sorry if I am too dumb to know, but where I am supposed to find "mkfs.jffs2" on OpenSUSE 12.1?

It used to be in "mtd-utils", but I could not find it for 12.1 and neither any package providing "mkfs.jffs2" on "" or any other public repository.

Have things changed so much that "mkfs.jffs2" is no longer used?
If so, how should I proceed to generate a JFFS2 image?

Thanks a lot.
