Change SWAP-device to SWPdevice for labels none

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

           Device Boot      Start         End      Blocks   Id  System
/dev/cciss/c0d0p1   *           1          13      104391   83  Linux
/dev/cciss/c0d0p2              14        1057     8385930   83  Linux
/dev/cciss/c0d0p3            1058        1318     2096482+  82  Linux swap
/dev/cciss/c0d0p4            1319        4427    24973042+   5  Extended
/dev/cciss/c0d0p5            1319        1840     4192933+  82  Linux swap
/dev/cciss/c0d0p6            1841        2101     2096451   83  Linux
/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):
anaconda CVS

How reproducible:
Always

Steps to Reproduce:
1. Kickstart hardware with cciss driver
2. Specify 2 or more swap partitions
3.
  

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.

Additional info:

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.
Comment 2 David Cantrell 2006-02-01 18:45:15 UTC 
Patched fsset.py to use "SW-%s" for cciss partitions, but keep the "SWAP-%s"
naming method for non-cciss partitions.
