   |  main: control_start: No such file or directory
 
 This is obviously the problem, unfortunately it is a
 singularly useless error message, what it seems to be
 indicating is that something went wrong with creating the
 control socket (which looks to be the thing that the unpriv'd
 part of dhcpcd uses to communicate with the part that is
 still root)
 
 No idea what necessarily, the "No such file or directory" will be
 from an unlink attempt failing, and not the actual error.
 
 But do you have a /var/run/dhcpcd directory and if so, what is
 its owner/group/permissions ?   (ie: ls -ld /var/run/dhcpcd )
 
 If I had to guess, you have it owned by root, where now it
 needs to be owned by _dhcpcd so the socket can be created by
 an unpriv'd user.
