Public bug reported:

Using Ubuntu 16.04 (or any system with systemd)

Current status:
boinc-client shows up as costing 1 second at boot with systemd-analyze blame due to sleep 1 in service file.   I'm guessing this is to try and make  boinc have less impact on bootup (it does afaict).  If there is a different reason this might all be moot :).

Proposal I'm looking into:
Using systemd timers to tell boinc to start running X amount of time after bootup.

Something like:
Description=Runs boinc-client service after bootup



Description=Berkeley Open Infrastructure Network Computing Client

#ExecStartPre=/usr/bin/touch /var/log/boinc.log /var/log/boincerr.log
#ExecStartPre=/bin/chown boinc:boinc /var/log/boinc.log /var/log/boincerr.log
ExecStart=/usr/bin/boinc --dir /var/lib/boinc-client
ExecReload=/usr/bin/boinccmd --read_cc_config
ExecStopPost=/bin/rm -f /var/lib/boinc-client/lockfile

With the following boinc-client is no longer in the blame list at all!
I disabled the ExecStartPre because boinc-client seemed to start them earlier.
I choose 25s at random for my slow test machine.  I'm not sure the best value there.

[1]  man systemd.timer
OnActiveSec=, OnBootSec=, OnStartupSec=, OnUnitActiveSec=, OnUnitInactiveSec=
           Defines monotonic timers relative to different starting points: OnActiveSec= defines a timer relative to the moment the timer itself is activated.  OnBootSec= defines
           a timer relative to when the machine was booted up.  OnStartupSec= defines a timer relative to when systemd was first started.  OnUnitActiveSec= defines a timer
           relative to when the unit the timer is activating was last activated.  OnUnitInactiveSec= defines a timer relative to when the unit the timer is activating was last
