The '#' is being put out by "multipath -l" if it can't find the necessary
information in sysfs. This only helps testing, so I can leave this out,
but it does now harm either.

Well, in an ideal world against an EMC Clariion but since this one sits
behind a firewall and the servers attached to it have a hard time
getting up to date packages and since I don't have this at home I use
KVM and a hacked up hw-detect that puts out a multipath.conf like:

defaults {
    getuid_callout /bin/scsi_id.sh
}

blacklist_exceptions {
    devnode "^hda"
}

defaults {
    user_friendly_names yes
}

Once I cleaned up the grub-install patch I put out an image for testing.
