Public bug reported: In automatically encrypted Clevis+Tang unlock of LUKS encrypted device (dmcrypt/cryptsetup) - on top of which the ZFS Pool for / resides, dhcpcd is used in order to obtain automatically an IP address during initramfs boot.
During this phase, dhcpcd is called before interfaces have carrier causing a 29 seconds boot delay. Boot delay is currently 45 seconds, instead of the 15 seconds that it should. BUG Initially reported in: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/2064926 Relevant Logs: ``` dhcpcd-10.0.6 starting [...] no interfaces have a carrier exiting due to oneshot dhcpcd exited Sleeping 29 seconds before retrying getting a DHCP lease dhcpcd-10.0.6 starting ``` A possible workaround would be to manually edit /usr/share/initramfs-tools/scripts/functions Changing this: `for ROUNDTTT in 30 60 90 120; do` To this: `for ROUNDTTT in 5 5 5 5; do` But the proper solution would be to continuously "scan" the state of the Interface (every Second or so), and wait until the interface is UP, before deciding to call dhcpcd. ** Affects: dhcpcd (Ubuntu) Importance: Undecided Status: New ** Attachment added: "initramfs_v4.debug" https://bugs.launchpad.net/bugs/2065037/+attachment/5775838/+files/initramfs_v4.debug -- 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/dhcpcd/+bug/2065037/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
