The systemd-analyze tool requires that all boot services are completed before the tool can be run successfully. If there are still outstanding services active, then the following error will be returned:

root@yocto-platform1:~# systemd-analyze 
Bootup is not yet finished. Please try again later.


To find out what services are still active, the systemctl list-jobs command can be used, e.g.

root@yocto-platform1:~# systemctl list-jobs 
1 multi-user.target start waiting 
102 rsync-appdatas.service start running
82 sync-rtc-to-sys-clock.service start running
83 systemd-update-utmp-runlevel.service start waiting 4 jobs listed.

These services can then be stopped as required:

root@yocto-platform1:~# systemctl stop rsync-appdatas


A service which has not compete at start-up will need to be investigated. Once possible cause the the mis-configuration of a custom service which is started at boot time, and is expected to behave as a traditional unix daemon by running continuously after boot has completed. For these types of services they should be configured as Type=forking.
