Maybe you could use the pidof utility, which comes with sysvinit
(which is Essential: yes package)?

 is there a convenient way to check the installed version of dhcpcd
 someway?

From the packaging manual:

 3.   1.   If the package is being upgraded, call:
new-preinst upgrade old-version

 When we configure a package (this happens with `dpkg --install', or
 with `--configure'), we first update the conffiles and then call:
  postinst configure most-recently-configured-version

So, you could put something like this in the preinst:

if [ $1 = upgrade -a $2 ]; then
  whatever you need to do
fi

Or this in postinst:

if [ $1 = configure -a $2 ]; then
  whatever you need to do
fi

And yes, this question would be more appropriate for debian-mentors
list.

As others have said, check the arguments to your postinst. Here's
an example excerpt:

if [ $1 = configure -a -n $2 ]  dpkg --compare-versions $2 lt 
3.0pl1-43 ; then

echo This is an upgrade from an old version -- restart daemon
fi

Of course, you'd replace 3.0pl1-43 with the version number of the
*first* version that *doesn't* need to perform the special action.

Being new the development group, I'm not sure if this is best asked
here or on debian-mentors... so please let me know if this thread
should start elsewhere.

Thanks,
