All returns Ext4.

What filesystem type is the root mounted with, when you use
initramfs-tools 0.120? (Check in /proc/mounts.)

# cat /proc/mounts
sysfs /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0
proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0
udev /dev devtmpfs rw,relatime,size=10240k,nr_inodes=254169,mode=755 0 0
devpts /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0
tmpfs /run tmpfs rw,nosuid,noexec,relatime,size=205288k,mode=755 0 0
/dev/root / ext4 rw,relatime,errors=remount-ro,data="" 0 0
tmpfs /run/lock tmpfs rw,nosuid,nodev,noexec,relatime,size=5120k 0 0
pstore /sys/fs/pstore pstore rw,relatime 0 0
tmpfs /run/shm tmpfs rw,nosuid,nodev,noexec,relatime,size=799340k 0 0

What does '/usr/lib/klibc/bin/fstype /dev/md0' show?

# /usr/lib/klibc/bin/fstype /dev/md0
FSTYPE=ext4
FSSIZE=33361625088

What does 'blkid /dev/md0' show?

# blkid /dev/md0
/dev/md0: UUID="5a290e58-0d5e-46aa-8e07-019526f4499f" TYPE="ext4"
