Partition types are sometimes used by operating systems and utilities to determine the type of a file system. The Linux kernel likely uses another means of determining if a swap partition is really swap. But it may simply assume that it is swap. Info on partitions and partition types: http://tldp.org/HOWTO/Partition/ I found some good information on partitions and memory management here, but no details on why specific partition types are used: http://tldp.org/LDP/sag/html/index.html Eric Martin wrote:

I know that partition types do something, as there are windows hidden partition types which are different from the standard windows partition types. Other than that I'm as curious as you.

Hi all, I have a bunch of linux boxes that have the swap partitions that are not of type swap. They are type linux. The OS seems to be swapping just fine on this partition type.

Some machines have swap partition that look like this from fdisk

/dev/hda6 50810 52890 1048792+ 82 Linux swap

Other machines have swap partitions that look like this.

/dev/hda6 50810 52890 1048792+ 83 Linux

Does anyone have experience with why it would or wouldn't cause issues? Does anyone know what it means to have a partition of type x or y? Is there a difference or is having a partition type mostly there for humans. I would have thought that the partition just defined the limits. Everything else depends on what you do with the partition as far as formatting and defining inodes/FATs and labels...

Any ideas?

Thanks,

Arturo
