However at present it is very convenient that one can share the swap partitions with Linux on a dual boot machine (at the price of running mkswap in the Linux boot scripts). I don't clearly see the benefit coming from enforcing the partition type. After all you should be able to do whatever you like with a chunk of your hard disk, for example cyclic buffers for inn, database space for databases working on raw disk, etc. space for ZFS which doesn't care about partition type (i have a ZFS partition which is marked of type Linux fs) and obviously swap. -- Michel TALON
