Description of problem:
The condition check in rc.sysinit for LVM

if [ -e /proc/lvm -a -x /sbin/vgchange -a -f /etc/lvmtab ]; then

because at this point /proc/lvm fails the existance check. Removing this check 
loads the volume groups properly

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


How reproducible:
Always

Steps to Reproduce:
1. Create a vg, lv, then put a file system on it.
2. Enter the file system into /etc/fstab
3. Reboot
4. Boot fails and drops to single user mode because the disk is unavailable. 

	

Actual Results:  Boot fails to complete, leaves machine in single user mode 
because mount -a fails. (Because LVM does not load, the volume in /etc/fstab is 
not available) 

Expected Results:  Boot to normal runlevel

Additional info:

I believe that once in runlevel 1 (Single User Mode), the /proc/lvm directory 
does exist, which makes troubleshooting the problem annoying. 

Since this could cause a system to fail to boot, I'm classifying it as a "High" 
bug, though I believe LVM is officially "not supported" the fact that the stock 
rc.sysinit attempts to load it merits consideration.
