http://bugzilla.opensuse.org/show_bug.cgi?id=993516 http://bugzilla.opensuse.org/show_bug.cgi?id=993516#c8 --- Comment #8 from Donald Curtis --- The workaround "set DHCLIENT6_MODE=managed in ifcfg file" didn't change anything (in my case). ------------------------------------------------------------- But, taking points made by Nirmoy I checked the contents of /etc/sysconfig/network/ and made the following changes: - In "config" decreased WAIT_FOR_INTERFACES from '30' to '8'. - In "dhcp" made the following changes: * DHCLIENT_RELEASE_BEFORE_QUIT and DHCLIENT6_RELEASE_BEFORE_QUIT set to "yes". * DHCLIENT_WAIT_AT_BOOT and DHCLIENT6_WAIT_AT_BOOT decreased from '15' to '4'. Additionally I commented out an extraneous DHCLIENT_SET_DEFAULT_ROUTE='yes' in ifcfg-enp2s0. The DHCPv6 lease is now committed 4 seconds after the Ethernet interface is up. And, the wicked service is now taking only 6.610s at boot. I'll attach the filtered Journal from this boot. ** I'll add a comment to Bug 975933. -- You are receiving this mail because: You are on the CC list for the bug.

Time between the kernel loading the driver and systemd starting wicked: 5 s. Time between wicked being started and acknowledging the interface as being "up": 7 s. Time between wicked acknowledging that the interface as being "up" and the DHCPv6 lease being committed: 3 s. -------------------------------------------------------------------- Given 8 s between the kernel loading the driver and acknowledging the link as being up/ready, the value of 8 s in config:WAIT_FOR_INTERFACES is possibly too tight -- I'll increase it to 10 s. The values of dhcp:DHCLIENT_WAIT_AT_BOOT and dhcp:DHCLIENT6_WAIT_AT_BOOT could be increased to 5 s but, I can't see any reason to do so: - there seems to be only a requirement that WAIT_FOR_INTERFACES is at least double the value of the DHCP client "wait at boot" times. -------------------------------------------------------------------- One point that should maybe not be overlooked is that, the AVM FRITZ!Box 7490 DSL Router (and possibly other AVM models as well) seems to need the DHCP clients to sign off (release) before the DHCP client shuts down. -------------------------------------------------------------------- Does this "wicked tuning" procedure need to be documented? -- You are receiving this mail because: You are on the CC list for the bug.
