Oh, I see. In the meantime I've discovered another possible reason for
the hassle. I removed the old GNU/Hurd partition with GNU parted and
re-created it. Parted said, I had an "unusual" partition table which
might cause probs with some boot loaders. In fact, the physical location
of the partitions doesn't conform with the partition numbers. 


The output
of fdisk -l /dev/hdc is as follows:

Disk /dev/hdc: 20.4 GB, 20496236544 bytes

Partition table entries are not in disk order

Linux doesn't seem to care about this, so I never bothered correcting
it. But could it be that this gives either gnumach or hurd a headache?

I reinstalled a minimal GNU/Hurd system with gnu-latest.tar.gz. Now,
fschk fails and says it was unable to determine if the partition was
mounted and that the physical size of the device does not conform with
the partition table entry. Under GNU/Linux, though, I see no such
errors.

What would be the easiest way to correct this - if it is indeed the
reason for the failure? I was thinking about backing up hdc1, removing
the swap partition (hdc2) and then enlarging the extended partition to
re-create the removed partitions there (i.e. the former hdc1 and hdc2).
But AFAIK parted is unable to resize (enlarge) extended partitions,
isn't it? Is there another tool that does this safely?

Thanks,
