dracut-0.5: initrd file is big

[Steven I Usdansky]

Command lines:
 1. none (initrd generated when kernel installed)
 2. dracut -a debug /boot/test-$(uname -r) $(uname -r)
 3. dracut  /boot/test2-$(uname -r) $(uname -r)
 4. dracut -H  /boot/test3-$(uname -r) $(uname -r)
File sizes:
 1.  3096635 initrd-2.6.31-0.67.rc2.git9.fc12.i586.img
 2. 14855892 test-2.6.31-0.67.rc2.git9.fc12.i586
 3. 14266231 test2-2.6.31-0.67.rc2.git9.fc12.i586
 4.  4743758 test3-2.6.31-0.67.rc2.git9.fc12.i586
 
test3 is 53% larger than initrd. Any way to shrink it?
