thanks.
when will systemd run "generators"? In the beginning of the boot ?
I can't see "sysv-generator" in /src/core/main.c

how is Systemd support both sysV's runlevel script and systemd's target file at
the same time?
systemd first runs its "generators", which generate .mount units from
/etc/fstab (systemd-fstab-generator), .service units from /etc/rc?.d
(systemd-sysv-generator), and so on.
(The auto-generated units live in /run/systemd/generator; the
package-distributed ones in /usr/lib/systemd/system; the user-provided ones in
/etc/systemd/system.)
systemd then starts with "default.target" (usually symlinked to
multi-user.target), creates a dependency tree (based on Wants= or Requires= in
the unit files, symlinks in *.wants/, or drop-ins in *.d/), and starts all
units that default.target depends on:
$ systemctl list-dependencies multi-user.target
multi-user.target
├─apache2.service
├─bind9.service
├─binfmt-support.service
├─cron.service
├─dbus.service
