Fsck checks all FS on every boot

[Petr Hejl]

Binary package hint: util-linux

Using xubuntu natty daily with all updates. util-linux-ng 2.17.2
Every time I boot fsck is performed on all filesystems - this include /boot (ext4), / (btrfs), /home (btrfs). The boot is terribly slow. /boot and /root are both ok, /home contain an error. The system boots ok.

I tried:
sudo init 2
sudo /etc/init.d/umountfs stop #unmounted swap, home
sudo mountall

Yet all the filesystems were fscked anyway (on mount all). I also tried changing uuids in fstab to /dev/sdX, but with no luck.

The problem is even worse with btrfs subvolumes (for example one subvolume for / and one for /home) on same fs - the fs is checked twice on every startup.
