Bug Description

vdfuse claims in it's usage note:

    "-t specify type (VDI, VMDK, VHD, or raw; default: auto)"

However it does not handle raw disk images, and fails in the following sequence:

    mkdir mnt
    vdfuse -f partitionedDisk.img mnt/

with:

    "ERROR: cannot autodetect disk type"

I verfied my image and found a work around via:

    mkdir mnt
    xmount --in dd --out vdi partitionedDisk.img mnt/

    mkdir mnt2
    vdfuse -f mnt/partitionedDisk.vdi mnt2

Which produces

    mnt2/Partition1

which is itself mountable.

The offending code seems to be:

    virtualbox-ose/debian/vdfuse/vdfuse.c:265&481

"raw" or rather "RAW" is never checked for.

there is a "RAW" backend for handling the image type.

I'll make a patch if there's a chance that it will be accepted.

I want to make sure this doesn't get lost/forgotten about. Is there a mailing list I can post to to.

There doesn't seem to be an upstream for this portion of the code.

Can I adopt it somehow?

This is really unfortunate that fixes with proposed patches die this way.

How can developers willing to spend time reporting and fixing bugs expect that their effort is worth while when such effort goes unresponded to?
