Description of problem:
If i install RHEL 4 U2 on an HP Proliant server with CCISS hardware RAID and I specify two swap partitions, the labels Anaconda places on the swap partitions are confusing:
LABEL=SWAP-cciss/c0d0p swap swap defaults 0 0
LABEL=SWAP-cciss/c0d01 swap swap defaults 0 0
Anaconda appears to take the swap device (i.e. /dev/cciss/c0d0p3), prepend swap and cut off a few digits of the device to fit it into a 16-character space (I have read bug 127892). If I run fdisk -l, I see two swap partitions:
Disk /dev/cciss/c0d0: 36.4 GB, 36413314560 bytes
255 heads, 63 sectors/track, 4427 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/cciss/c0d0p7 2102 2362 2096451 83 Linux
I have no way to know if label SWAP-cciss/c0d0p is really c0d0p3 or p5. To my knowledge, there is no equivalent to e2label I can run on an existing partition and extract the swap label. mkswap -L is used to create the label only.
I would like to request that the label be condensed as much as possible such that the full c0d0p3 or c0d0p5 fits. For example, SWAP could be reduced to SWP. The - could be removed as well, making for LABEL=SWPcciss/c0d0p3 with one character to spare.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Kickstart a machine.
2. Specify two or more swap partitions
Actual Results: Swap labels are difficult to use in order to narrow down which label is which partition.
Expected Results: Anaconda's swap labels should be shortened such that more of the actual device name fits in the 16-character limitation.

Reduce swap label from SWAP-device to SWPdevice
This simple one-line patch allows me to have two swap devices on HP cciss
storage and know exactly which is which. Here is a snippet from fstab:
LABEL=SWPcciss/c0d0p3 swap swap defaults 0 0
LABEL=SWPcciss/c0d0p7 swap swap defaults 0 0
