Howdy,

Well, this is what I am thinking about jumping into.  Ya'll ready for
this?  I'm thinking about redoing my partition layout.  I'm wanting to
keep / (root) on a normal ext4 file system.  I want to put /usr, /var,
/home, and such on LVM.  I been using that dracut thingy to build the
init thingy.  Sorry, I'm full of thingys tonight.  Maybe I need my meds?
 Anyway, the init thingy seems to be working, I think.  I asked a while
back how to tell for sure but it didn't get any replies so I am not real
sure it is.  I do get this tho:

And grub looks like this:

title=Initramfs-new_kernel
root (hd0,0)
kernel /boot/bzImage-3.2.2-1 root=/dev/sda3 init=/sbin/init
initrd /initramfs-3.2.2-1.img

Does anyone think dracut is not working?  I need to make certain before
diving into the next step.

I have a second drive that is plenty large enough.  Thanks Kashani.  I
plan to move everything currently to the larger drive then just sort of
do a fresh install on my regular OS drive.

One question I have right off the bat, how do I tell dracut to mount
/usr?  I think it used to have a usr USE flag but that seems to have
disappeared during a upgrade.  Is it magic?  Does it need to mount /var
as well for logging?

Just for the record, dracut is the only way I could get a init thingy to
build and let me boot.  I tried different ways and they just didn't
work.  At least I think dracut is working which is a good start.  ;-)

I hope there is a few dracut users on here that have at least /usr on a
separate partition.

Thanks.

Dale
