It seems that there is no impact but Wheezy mount the rootfs twice.
In mtab or df (but not in mount)
rootfs / rootfs rw 0 0

ro,user_xattr,barrier=1,data=ordered 0 0
In FSTab, the mount point in only define once :
UUID=xxxxxxxxxxxxxxxxxxx / ext4 defaults,errors=remount-ro 0 1
It's a really small problem. Just layout issue.
% cat /proc/mounts | grep ' / '
rootfs / rootfs rw 0 0
/dev/disk/by-uuid/... / btrfs rw,relatime,ssd,space_cache 0 0
The root filesystem is only mounted once; this is the second line.
The first line "rootfs" is actually the initramfs from when the
system booted. The real root filesystem is mounted inside this
on /root, but it's not visible on the running system.
The only change here was that when /etc/mtab was a static file,
we didn't add the initramfs to it. But now that we use /proc/mounts,
the information which was previously hidden is now visible.

Ok, I was thinking it's mounted twice because "df" show me the same
space usage.
% df -H |grep -E '/$'
rootfs 14G 13G
2,0G 87% /
/dev/disk/by-uuid/xxxxxxww 14G 13G 2,0G 87% /
As It's my misinterpretation, you can close the bug.
