Details:

this was reported to debian as
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=542435

I am seeing this issue on Fedora with 1.97.2 and 1.98

devices in /dev/mapper/ show up in the format
lrwxrwxrwx.  1 root root      7 Apr 27 11:36 VolGroup00-LogVol00 -> ../dm-0
lrwxrwxrwx.  1 root root      7 Apr 27 11:36 VolGroup00-LogVol01 -> ../dm-2
lrwxrwxrwx.  1 root root      7 Apr 27 11:36 VolGroup00-LogVol02 -> ../dm-1

1.98 shows the following behaviour
grub2-probe /
grub2-probe: error: cannot find a device for / (is /dev mounted?).

1.97.2 show the following behaviour
 grub2-probe /
grub-probe: error: cannot find a device for /.


the symlinks are created by udev rules provided by upstream lvm
