Details:

Originally submitted here : https://bugs.gentoo.org/show_bug.cgi?id=430748

This is a regression of 2.00 from 2.00-beta6

# /usr/sbin/grub2-probe /boot/grub2/
/usr/sbin/grub2-probe: error: unknown filesystem.
zsh: exit 1     /usr/sbin/grub2-probe -vvv /boot/grub2/

[The full log with -vvv is in attachment]

I have a dmraid (intel fake Raid) mounted like this : 
# mount
rootfs on / type rootfs (rw)
/dev/mapper/isw_ddbeejgcgd_Volume03 on / type ext4
(rw,noatime,discard,commit=0)
proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)
tmpfs on /run type tmpfs (rw,nosuid,nodev,relatime,mode=755)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)
cgroup_root on /sys/fs/cgroup type tmpfs
(rw,nosuid,nodev,noexec,relatime,size=10240k,mode=755)
openrc on /sys/fs/cgroup/openrc type cgroup
(rw,nosuid,nodev,noexec,relatime,release_agent=/lib64/rc/sh/cgroup-release-agent.sh,name=openrc)
cpu on /sys/fs/cgroup/cpu type cgroup (rw,nosuid,nodev,noexec,relatime,cpu)
udev on /dev type devtmpfs
(rw,nosuid,relatime,size=10240k,nr_inodes=1011443,mode=755)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620)
shm on /dev/shm type tmpfs (rw,nosuid,nodev,noexec,relatime)
/dev/mapper/isw_ddbeejgcgd_Volume01 on /boot type ext2 (rw,noatime,discard)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc
(rw,noexec,nosuid,nodev)

a device.map like this: 
(hd0)   /dev/mapper/isw_ddbeejgcgd_Volume0

I startup my array from an initramfs with that : 
echo "Detect the raid arrays ..."
/sbin/dmraid -ay || rescue_shell
/sbin/dmsetup.static mknodes || rescue_shell


Reproducible: Always

Actual Results:  
see log attached

Expected Results:  
As with the beta6 (with exactly the same system, same config files): 
# /usr/sbin/grub2-probe /boot/grub2/    
ext2
[The full log with -vvv is in attachment too for comparison]

I tried the head of the development tree and it is the same behavior as the
2.00
