No dhcpcd process after resuming from hibernation after stand-by

[acarstoiu]

My machine is configured to enter hibernation after spending some time in the stand-by state. Whenever it resumes from hibernation in this scenario, dhcpcd is not running.

If I put the machine into hibernation directly, everything works correctly after resume. Only the automatic hibernation ordered by elogind (I'm on Gentoo Linux) produces the problem.

Steps to Reproduce:

1. Let the machine enter in stand-by (as set by the desktop environment).
2. Let it hibernate ("HibernateDelaySec" setting in /etc/elogind/sleep.conf).
3. Wake up the computer.
   No DHCP client is running, although wpa_supplicant connects immediately to the available wireless network.

Someone discovered that this is actually related to the 10.3.* versions of dhcpcd and not a fault of netifrc. See this comment with his findings.

Yours might not be exactly the same, but the Gentoo discussion you linked might be indicative of a bug just addressed in #596, based on eloop and the single-interface dhcpcd mode. It's not perfect parity--the forum post indicates a coma, and this issue seems to imply the process just dies--but if you want to try it, a fix just landed in master.
