Subject: [PATCH e2fsprogs] - ignore bind mounts in fsck

An entry like this in /etc/fstab:

/foo	/bar	ext3	bind,defaults	1 3

will stop boot, as fsck.ext3 tries to check it and fails:

e2fsck 1.40.2 (12-Jul-2007)
fsck.ext3: Is a directory while trying to open /foo

The superblock could not be read or does not describe a correct ext2
filesystem. ...

Granted, asking for fsck of a bind mount in the fstab is a bit odd, 
but it doesn't seem like it should stop the boot process if you make
this mistake.
