dhcpcd error

this message is left in my logfile when dhcpcd tries to start:
dhcpcd[115]: writePidFile: fopen: No such file or directory

Does anyone know what this means? What would writePidFile be trying to write? How would I find out what it is trying to write?

I ran strings on dhcpcd and it looks like the pid files are put in /var/run. The %s is replaced with the network interface. (eth0, eth1, ppp0, etc... )

Code:

# strings dhcpcd | grep pid 
waitpid
/var/run/dhcpcd-%s.pid
/var/run/dhcpcd-%s.pid

A pidfile is a text file with the _P_rocess _I_D_ for an application. This is useful for when it is time to do a graceful shutdown of the application or the entire system. Applications which create a pidfile when they start do not all use the same location in the file system for creating the pidfile and it seems that with your current system, dhcpcd is trying to create its pidfile in a directory that is not there. If crabboy is right, and I have no reason to doubt him, you need to create a /var/run directory in your file system, so that dhcpcd (and probably many other apps) can write the pidfile there.

cool, thanks for that insight. I know I definately have a /var/run directory though. Could the name of the accual pidfile directory be found in the dhcpd.c source file? I'll check.
