I do have the type set to 0xfd.  Others have said that auto-assemble only

expected the same behavior when I built this array--again using mdadm
instead of raidtools.
Any md arrays with partition type 0xfd using a 0.9 superblock should be
auto-assembled by a standard kernel.

no... debian (and probably ubuntu) do not build md into the kernel, they build it as a module, and the module does not auto-detect 0xfd. i don't know anything about slackware, but i just felt it worth commenting that "a standard kernel" is not really descriptive enough.

Good point - I should have mentioned the non-module bit!
