I've used dnscache for network service dependencies (and cygserver and syslog-ng
for other Cygwin services) with delayed start and preshutdown (cygrunsrv -O,
--preshutdown).
Where previous usage was cygrunsrv -t, --type manual is now called demand
service startup type.

You can set service startup type using:

$ sc config cygsshd start= boot|system|auto|demand|disabled|delayed-auto
# option flag requires = and the value must be a separate argument

and check them using:

$ sc query cygsshd

SERVICE_NAME: cygsshd
        TYPE               : 10  WIN32_OWN_PROCESS
        STATE              : 4  RUNNING

        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0
$ sc qc cygsshd
[SC] QueryServiceConfig SUCCESS

                           : cygserver
                           : syslog-ng
        SERVICE_START_NAME : LocalSystem

$ regtool -pv list
/proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/cygsshd/
...
Start (REG_DWORD) = 0x00000002 (2)		# [auto]
DelayedAutostart (REG_DWORD) = 0x00000001 (1)	# [delayed]
...
$ regtool -pv list

...
Preshutdown (REG_DWORD) = 0x00000001 (1)	# [preshutdown]
...

As the reg entries show, you can also do this by adding or setting registry
entries using Cygwin regtool, Windows reg, or regedit commands.
