Description of problem:

In /etc/rc.d/rc.sysinit , swapon is called before devlabel,
so swapon might try to use the wrong device file, in case the swap device file
is managed by devlabel ( recommended if you change the disk drives a lot )

Line 338 :
action $"Activating swap partitions: " swapon -a -e

Line 501 :
if [ -x /sbin/devlabel ]; then
        /sbin/devlabel restart
fi

Line 662 :
# Now turn on swap in case we swap to files.
swapon -a
action $"Enabling swap space: " /bin/true

The second swapon will "catch" the devlabel managed swap device, but the fisrt
might still try to access a wrong one ( because the symlink has not yet been
updated by devlabel and points to the old, possibly wrong device )

Version-Release number of selected component (if applicable):

initscripts-7.14-1

How reproducible:


Steps to Reproduce:
1. setup a devlabel managed swap device :
  - mkswap /dev/hdxy ( for example hda1 )
  - devlabel add -d /dev/hda1 -s /dev/swap1
( /dev/swap1 is now a symlink to /dev/hda1 )
  - add /dev/swap1 into /etc/fstab
2. make your swap disk change its name ( change from master to slave , or place
on different channel ) , let's assume it was hda before and is hdc now
3. boot
    
Actual results:

The first swapon call will try to use /dev/hda1 ( the symlink still points to it )

Expected results:

devlabel is run before swapon and updates the symlink to point to /dev/hdc1.
swapon has no error.
