[Bug 1711011] Re: fsck.jfs may be attempted before multipath devices are available

[Mathieu Trudel-Lapierre]

Nope, that's wrong. fsck.jfs is there in xenial, but apparently not
there in artful. This needs further investigation.

  I haven't investigated more than that, it looks like jfsutils does not include anything to copy fsck.jfs to the initramfs. Clearly hooks/fsck in initramfs-tools appears to not be doing its job in this case.
