In /usr/src/sbin/init/init.c:

        if ((session_db = dbopen(NULL, O_RDWR, 0, DB_HASH, NULL)) == 0) {
                emergency("session database open: %m");
                return (1);
        }

(Then when that "start_session_db()" fails, init does the single_user
instead of multi_user.)

Again, I don't know if dbopen(NULL, ...) uses memory or disk for the
temporary database. But now, I think I am wrong, because looking at
src/lib/libc/db/hash/hash.c doesn't indicate any opening of files with it
is NULL.
