It's a lot safer to simply look for the signature of the partition content to see what it is. It's how md and lvm is detected, so why not swap and ext2/3/4? What "format" (presuming you mean mkfs) reads the partition type? I cannot find anything in man pages or anything that indicates it reads anything to determine the filesystem type. Ie. how would it access the partition table if you do "mkfs /dev/sda2"?? The table is on /dev/sda not 2. > Of course one can create a DOS partition, for example, then reformat it > as a Linux one using an EXT3 file system, as an override, and the system > won't care what the partition type was.

It would be interesting to see an example - so far I've never seen any indication it uses it, not even during upgrade/installation. -- Best Regards Peter Larsen Wise words of the day: I have a map of the United States.
