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 "http://software.opensuse.org/search" 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.
