The "-K --noipv4ll" is the solution. Looking at initramfs_v9.debug, dhcpcd is only called once and you do not see any "Sleeping" log messages.
initramfs_v10.debug takes longer because it calls dhcpcd twice. The first call is killed due to "timed out". initramfs_v11.debug calls dhcpcd three times. The first two calls are killed due to the timeout. So you do not want to have a too short timeout to kill a perfectly running dhcpcd client. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065037 Title: dhcpcd is called before interfaces have carrier causing a 29 seconds boot delay To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/2065037/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
