Enumerating partitions, then "Error: Aborting: no partition table found."

As a heads-up: for the moment we only make the first 9 partitions available.
If you need to access a partition beyond that you need to apply something
like [1] and rebuild Sculpt.

You will get this error if 'part_block' could not make use of either the
MBR or GPT. It parse the table and makes note of each valid partition it
encounters [2], [3]. For whatever reasons none of them appears to be valid.

[2] repos/os/src/server/part_block/mbr.h:273
[3] repos/os/src/server/part_block/gpt.h:431

- What kind of partition table type do you use?
- In case of MBR do you only use extended partitions?

If you like contact my off-list and provide the complete table (LBA,
size and type is sufficient).

Josef
