You don't need an initial ram disk at all, if you don't want to have root
on a logical volume.

Just run "vgscan;vgchange -ay" in your startup script before it comes to local
filesystem mounts.

LVM doesn't care. Quotas are FS things.

Then something with the LVM driver (in case you build it into your kernel),
the /linuxrc script content in your initrd or the boot configuration to boot
the kernel containing LVM is wrong.
In case your boot kernel is stored in the root filesystem on a logical
volume as well, you need to patch lilo and probably LVM as well.

Search the LVM archive at www.sistina.com for that.

root on LV is only recommended if you *really* need it.
It is rather hard to configure.
We are working on boot time recognition of VGs which will make it much easier.
