Alguma ideia de por que estou recebendo este erro?

O site do Arch Linux tem uma notícia que explica isso:

News: filesystem upgrade - manual intervention required

2011-12-20 - Tom Gundersen

When upgrading to filesystem-2011.12 there will be a conflict with /etc/mtab.

Install the package as follows:

pacman -S filesystem --force

It is strongly advised to avoid the --force or -f switch as it is not safe. However, in this particular case it is needed as deleting /etc/mtab manually would break pacman.

The reason for the conflict is that the file used to be generated at boot and hence not owned by any package. Now it is a symlink to /proc/self/mounts owned by filesystem. This change means that initscripts no longer requires write access to the rootfs (though other packages might).
