 No, I was talking about "filesystem" label. That's why I wrote that
e2label doesn't do it. Apparently, FC3 sets labels for swap partitions
somehow. In fact swapon has 2 options to find a swap device - either a
device name or a label in format LABEL=name. Anaconda set label
automatically for swap device as SWAP-hdb2 (in my case).
