isn't swapspace supposed to be on a 'b' partition?  Are you using swap 
on a slice 10?  how is that possible when the i386/amd64 BIOS can't see 
more than 4 primary partitions?

Kris, would you mind giving input to this?  How can there be a s10, and 
how can you add swapspace to a device that isn't a partition 'b' nor a 
file backed swapspace?  Those were the only two ways I thought was 
supported for swap.

Dieter, does my questions above sound to be a correct interpretation of 
your disk setup?


thanks!
