Very strange. This boot it worked. I did not change anything. I will keep an eye on that.
> cat: /run/dhcpcd/resolv.conf.enp2s0.ipv4ll: No such file or directory That is the error I am very interested in fixing. It implies an error in 20-resolv.conf but damned if I can see it!
Can you attach your /etc/dhcpcd.conf as well please?
Created attachment 406480 [details] /etc/dhcpcd.conf /etc/dhcpcd.conf is the default one from net-misc/dhcpcd-6.9.1 . It fails sporadic every few boots. Even without the error message in rc.log now. "dhcpcd -4 enp2s0" seems to work always.
Could you try this patch please? http://roy.marples.name/projects/dhcpcd/vpatch?from=bba0ca7ae99aeae9&to=2a1546e5869468f1
I was also hit by this with dhcpcd-6.9.1, random failures of name resolution.

Jouni could you please test that too?
The patched version worked fine on four successive reboots, so I suppose the patch did its job!
My machine is also affected by this problem, except that the victim is emptied `/etc/ntpd.conf'; Roy's IPv4LL patch seems to resolve it successfully. I think that those who have deployed recent versions of dhcpcd need to check that their `resolv.conf', `ntp.conf' (and anything else which could be similarly affected) are still in desirable states. Though this seems to be already fixed upstream, there does not seem to be a deeper explanation, so I post my result of investigation for potential reference: It seems that the problem originated from a race condition on hooks triggered by IPv4LL: I hacked the `dhcpcd-run-hooks' script to add `set -x' and stdout/stderr redirection to a log file solely for the `50-ntp.conf' hook, and found the log (see following attachment; in particular note the lines following line 135) showing two interleaving IPv4LL sessions (line 135 and line 153) of that hook. In summary, the culprit seems to be file manipulation requiring but not checking atomicity.
Created attachment 407282 [details] log of 50-ntp.conf Above-mentioned line numbers should be replaced with 135 and 165, because I accidentally deleted the original log and thus need to reproduce the log with the same steps.

Comment on attachment 407282 [details] log of 50-ntp.conf Done; sorry for the inconvenience.
*** Bug 556810 has been marked as a duplicate of this bug. ***
dhcpcd-6.9.2 has been released which should now fix this issue.
