GRUB doesn't need access to any of LVM devices in my case! /boot with
kernel and initrd is on the separate partition (/dev/sda1 using ext3).
I'm talking about grub-probe an userland Linux program, which just
searches for filesystem type and uuid of the root and swap partitions.
This informations are used by update-grub Debian script and passed to
Linux kernel using root= and resume= kernel parameters on boot. Grub
doesn't need to interprete or read them in any way or access them in any
way on boot.
