It must have just been a failed upgrade, because I did a clean slate install of 15.10 beta2 and now the boot time is identical as it was in 15.04, (20 seconds.)

I'm not sure if the initrd time is included in this too? Because that could be the source of the additional time. But subjectively it feels about twice as long to boot as 15.04 on the same system. This is an upgrade from 15.04 to 15.10. --- ApportVersion: 2.18.1-0ubuntu1 Architecture: i386 CurrentDesktop: Unity DistroRelease: Ubuntu 15.10 InstallationDate: Installed on 2015-07-26 (56 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Release i386 (20150422) MachineType: LENOVO 20AR006RUS Package: systemd 225-1ubuntu4 PackageArchitecture: i386 ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.2.0-10-generic root=UUID=6e3af67c-126e-4f64-8004-8e87ef62201c ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 4.2.0-10.12-generic 4.2.0 Tags: wily UdevLog: Error: [Errno 2] No existe el archivo o el directorio: '/var/log/udev' Uname: Linux 4.2.0-10-generic i686 UpgradeStatus: Upgraded to wily on 2015-09-20 (1 days ago) UserGroups: adm lpadmin sambashare sudo _MarkForUpload: True dmi.bios.date: 06/22/2015 dmi.bios.vendor: LENOVO dmi.bios.version: GJET84WW (2.34 ) dmi.board.asset.tag: Not Available dmi.board.name: 20AR006RUS dmi.board.vendor: LENOVO dmi.board.version: SDK0E50510 PRO dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrGJET84WW(2.34):bd06/22/2015:svnLENOVO:pn20AR006RUS:pvrThinkPadT440s:rvnLENOVO:rn20AR006RUS:rvrSDK0E50510PRO:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 20AR006RUS dmi.product.version: ThinkPad T440s dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1497678/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
