I upgraded to dhcpcd-4.0.1-r1 last night from 3.2.3 and I notice that it created an empty /etc//resolv.conf instead of my usual nameserver 192.168.0.101 entry. Not sure if this is a configuration issue or a bug frankly. I run net-dns/djbdns-1.05-r21 (dnscache) and dhcpcd 3.2.3 dis correctly create the 'nameserver 192.168.0.101' entry in /etc/resolv.conf, but 4.0.1-r1 creates no entries -- just the head/tail comment. Here is my /etc/conf.d/net: dns_domain=( "lan.net" ) dns_search=( "lan.net" ) config_eth0=( "dhcp" ) dhcp_eth0="nodns" dns_servers_eth0=( "192.168.0.101" ) 3.2.3 creates the following (correct) /etc/resolv.conf: #Generated by net-scripts for interface eth0 domain lan.net search lan.net nameserver 192.168.0.101 but 4.0.1-r1 does not populate that file with any non-comment entries. Help! Reproducible: Always

Paolo, Did you test with USE=compat? That patch would require compat. Phil
I also tried the patch here and can report that it does not help. Still getting: # cat /etc/resolv.conf # Generated by dhcpcd # /etc/resolv.conf.head can replace this line # /etc/resolv.conf.tail can replace this line Here is my command line as reported by ps: # ps ax | grep dhcpcd 17994 ? Ss 0:00 /sbin/dhcpcd -h porthos -R eth0

After applying the patch, you'll need to STOP dhcpcd, restore /etc/resolv.conf and then restart dhcpcd. After that you should be fine.
I need /etc/resolv.conf to be created from the Gentoo /etc/conf.d/net file. With 3.2.3, you get exactly that behavior: # rm /etc/resolv.conf # /etc/init.d/net.eth0 restart # cat /etc/resolv.conf # Generated by net-scripts for interface eth0 domain lan.net search lan.net nameserver 192.168.0.101 Having 4.0.1-r1 not clobber an existing /etc/resolv.conf isn't enough.

(In reply to comment #13) > Having 4.0.1-r1 not clobber an existing /etc/resolv.conf isn't enough. Eh? That's exactly what earlier versions of dhcpcd do with with -R flag - they don't clobber /etc/resolv.conf and this patch enables that.
Your patch fixes the problem for me. My settings from dns_servers_eth2 now appear in /etc/resolv.conf instead of the blank file generated from dhcpcd.
I carefully reapplied the patch and rebooted this time. # cat /etc/resolv.conf # Generated by dhcpcd # /etc/resolv.conf.head can replace this line # /etc/resolv.conf.tail can replace this line I don't run anything other than dhcpcd, no resolvconf, no dnsmasq, nothing else. The patch does not work for me. If I mask off 4.0.1 and go back to 3.2.3, everything is fine, i.e. _somthing_ creates my /etc/resolv.conf if its missing and dhcpcd leaves it alone.

By don't you add a comment or restore /etc/resolv.conf to how it should be and then restart net.eth0? Then we will know if dhcpcd is still clobbering it for you OR baselayout isn't correctly creating /etc/resolv.conf

The comment I added is gone.
My previous comment was for 3.2.3, i.e. the version that works.

Created an attachment (id=166928) [edit] Skip hooks correctly. OK, this new patch works with config in comment #6. Does this fix everyone?

The new patch works for me too.
4.0.2 is in the tree with the fix now, will fast-track to stable.
