I don't see any point in having "you just fscked yourself" written to
the syslog.  At the same time, writing to a mounted device is actually
useful: it's currently the only way to write the boot block on an
ext2 filesystem (and Viro: if you start using the page cache for the
superblock in ext2, you probably have to add an explicit interface to
write the boot block at the same time!!!)
