When fsck is running, it usually happens in a mode where only /
is mounted read-only, and all other file systems (such as /usr
or /var) are not. So I'd say that fsck doesn't do logging
somewhere into /var/log because it doesn't exist at that time.
Single user mode is a state of heavily reduced system functionality,
but usually sufficient for solving file system problems.

Which is still risky, assuming that the file system has not
been marked clean.

And a good occassion to read more about UFS (McKusick et al.) - to
develop a better understanding of what's happening. :-)
