Inconsistent filesystem on boot, possibly because of failed unmount on shutdown

Bug Description

When booting grub complains about inconsistent file system and I have to boot in rescue mode to replay journal.

I'm guessing that the problem is related to the fact that some filesystem fails to unmount on shutodown. (Is this logged somewhere?)

Here's my fstab:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/hdb1 / reiserfs noatime,notail,user_xattr 0 1
/dev/hdb2 none swap sw 0 0
/dev/hdb3 /home reiserfs noatime,notail,user_xattr 0 2
/dev/hdc1 /home/shared ext3 noatime 0 0
/home/.var /var bind bind 0 0

#/dev/hdd1 /media/windows-c ntfs umask=0222 0 0
#/dev/hdd5 /media/windows-d ntfs umask=0222 0 0

Oh sorry for not commenting on this.

I think the problem had to do with my configuration of daemontools. It was configured to respawn at all runlevels making it impossible to unmount. So I have sinced fixed the issue by fixing that.

However, there might be reason to investigate a cleaner way of handling such situations for users not capable of taking care of it. For example makeing sure to sync all filesystems before shutdown even if unmount fails.

Linux kernel flushes all disk caches before going down. All the halt/poweroff/reboot call sync before proceeding. You can even see a message about it flashing extremely fast right before the reboot/whatever initiates. Only thing that you can add is forcing remount as read-only. That happens with Ubuntu as well. These measures already do pretty much everything that is possible, and at least I can't see anything else that would be doable.

I would instead of that focus on fixing the misbehaving applications. (daemontools?)
