Description of problem:
Duplicate of bug 170500 for FC development.
If i install Fedora or RHEL 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.

Steps to Reproduce:
1. Kickstart hardware with cciss driver
2. Specify 2 or more swap partitions
Actual Results: fstab contains labels that do not point straight to a specific partition.
Expected Results: fstab should contain swap labels with the full device name when possible.
This is a one-line patch to fsset.py and I would appreciate your consideration in this matter.
Created attachment 122390 [details]
Change SWAP-device to SWPdevice for labels
This patch allows labels to appear as follows in /etc/fstab:
LABEL=SWPcciss/c0d0p3 swap swap defaults 0 0
LABEL=SWPcciss/c0d0p7 swap swap defaults 0 0
Since I can now see the partition information (instead of c0d01), I know which
fstab entry is which partition.
Patched fsset.py to use "SW-%s" for cciss partitions, but keep the "SWAP-%s"
naming method for non-cciss partitions.
