Debian Define its runlevels this way

0 -- System Halt
1 -- Single user
2 -- Full multi-user mode (Default)
3-5 -- Same as 2
6 -- System Reboot

And RedHat defines its runlevels this way.

0 — Halt
1 — Single-user mode
2 — Not used (user-definable)
3 — Full multi-user mode
4 — Not used (user-definable)
5 — Full multi-user mode (with an X-based login screen)
6 — Reboot

-----------------------------------------------------------------------
So runlevel 4 is not used in RedHat


>> but why isn't vzctl stopped in runlevel 0 1 and 6?

The line '# Default-Stop: ' is part of SuSe init script header is 
ignored in SuSE.

 From man insserv
----------------------------------------------------------------------------------------------------------
insserv enables an installed system init script (`boot script') by read‐
ing the comment header of the script, e.g.:

### BEGIN INIT INFO
# Provides: boot_facility_1 [ boot_facility_2 ...]
# Required-Start: boot_facility_1 [ boot_facility_2 ...]
# Required-Stop: boot_facility_1 [ boot_facility_2 ...]
# Should-Start: boot_facility_1 [ boot_facility_2 ...]
# Should-Stop: boot_facility_1 [ boot_facility_2 ...]
# Default-Start: run_level_1 [ run_level_2 ...]
# Default-Stop: run_level_1 [ run_level_2 ...]
# Description: multiline_description
### END INIT INFO

and calculating the dependencies between all scripts. Please note, that
the Required-Stop, Should-Stop, and Default-Stop are ignored in SuSE
Linux, because the SuSE boot script concept uses a differential link
scheme (see init.d(7)).
