I was just thinking, there is a Linux extended partition (0x85).
Could we use that? It would probably screw up fdisk, but everyone
will be using parted anyway ;-) (Seriously: we could change fdisk)
No. 85 and F and 5 are just

Yes. It's called the "s_first_data_block" field in the ext2
superblock, and lets you offset the data zone from the start of the
filesystem.

Eeeeh. not quite.
Because we reserve the first 1024 bytes of an ext2 fs for putting the boot
loader, we put the superblock at offset 1024. For 1k blocks, this means
the superblock ends up

The answer to that is pretty simple --- you create a compatible

In the above I did not necessarily mean "outer extended" - the

I know this is messy, but: it's probably possible to fake it at

Argghh. Forget it.

This won't work in general, because DOS expects only one extended
