Description of problem:
- anaconda doens't create /etc/lvm (which is OK, I think)
- rc.sysinit doesn't setup LVM2 if /etc/lvm not present (IMO not OK)
- lvm vgscan --mknodes exits with code 5

Detailed error messages are in bug 118787 and bug 119964.

Version-Release number of selected component (if applicable):
initscripts-7.49-1
lvm2-2.00.08-5

How reproducible:
always after fresh-install and no manual intervention

Steps to Reproduce:
1. do a fresh install using LVM
2. start system
  
Actual results:
errors fully posted in bug 118787 and bug 119964


Expected results:
startup without errors

Solution:
vgmknodes should be called after vgchange -a y, not together with vgscan.
/etc/lvm shouldn't be a prerequisite (if we have lvm2 installed, why
shouldn't we try to run it?)
