Problem solved! Thanks to Robert Bonomi, Eckhard Rueggeberg, and Rory
Toma for their replies. The solution is described below.

After rc.boot does a fsck on all partitions it finds in /etc/fstab, it
calls rc.single (if fsck was successful). rc.single attempts to remount
all partitions as read/write. Attempting to mount /usr failed thus
sending an exit code of 2 back to rc.boot. rc.boot in turn exited into
single user mode. Commenting out the following lines in rc.single solved
the problem.

rc.single:
----------
(
        intr mount -o remount /
        if [ $? -ne 0 ]; then exit 1 ; fi
# intr mount -o remount /usr
# if [ $? -ne 0 ]; then exit 2 ; fi

        intr umount -at nfs
> /etc/mtab
        intr mount -f /
# intr mount -f /usr
