If the jfs module is blacklisted, then dracut cannot do anything. As I told you
in comment #3, dracut requires that the system it is called from has all the
necessary file system drivers loaded, and in addition in your case /dev/sda3
mounted as /.

BTW this file does not belong to dracut, this tool just generates the initrd,
it does not decide what kernel modules are unsupported on the system:

> $ rpm -qf /lib/modprobe.d/60-blacklist_fs-jfs.conf
> suse-module-tools-16.0.30-1.1.x86_64

> $ cat /lib/modprobe.d/60-blacklist_fs-jfs.conf

You can open a feature request against the kernel for this purpose.
