The code in question is main.c:

	if (hotroot()) {
		struct statvfs stfs_buf;
		/*
		 * We modified the root.  Do a mount update on
		 * it, unless it is read-write, so we can continue.
		 */
		if (statvfs("/", &stfs_buf) == 0) {
			long flags = stfs_buf.f_flag;
			struct ufs_args args;

			if (flags & MNT_RDONLY) {
				args.fspec = 0;
				flags |= MNT_UPDATE | MNT_RELOAD;
				if (mount(MOUNT_FFS, "/", flags,
				    &args, sizeof args) == 0)
					return FSCK_EXIT_OK;
			}
		}
		if (!preen)
			pwarn("\n***** REBOOT NOW *****\n");
		sync();
		return FSCK_EXIT_ROOT_CHANGED;
	}

I don't see anything wrong with it. Can you add some debugging to see
what's going on?
