Why does systemctl status cause the unit to be unloaded?
Since nothing has a dep on your unit, “systemctl status” hence will cause the unit to be loaded, and then immediately unloaded again, as after that operation is complete there’s no further reason to keep the unit around…
How to change Linux boot target to multi-user?
Even after the Linux system is booted to a target, you can change it to another target/runlevel. For example, to change Linux to “multi-user” target: The command used is isolate. It starts the unit specified on the command line and its dependencies and stop all others.
Why are user services not starting automatically in systemd?
If the service the timer triggers was supposed to run, and with Persistent=true is most likely the case, systemd will start the manager for the user and reach the default target, and will start the timers/services. But after some seconds pam will complain about timeout and the manager service for the user will die with SIGRTMIN+24.
Why does graphical.target as the default systemd target?
Although, we should ask again about this fact, because the graphical.target depends of the multi-user.target, there is no need to all this stuff. It sound enough weird. But after this reduction, it remains one service, the accounts-daemon.service, like Rinzwind pointed out in its comment.

How to analyze the boot time of a system?
As you can see from the above output that each unit is sorted based on the time taken, you can simply find out which service is taking longer time while booting and analyze the issue. Next, we can also view a tree of the time-critical chain for the default target or a list of specified units with the critical-chain sub-command as shown.
Which is the default.target file in SystemV?
The default.target file is a symbolic link to the true target file. For a desktop workstation, this is typically going to be the graphical.target, which is equivalent to runlevel 5 in SystemV. For a server, the default is more likely to be the multi-user.target, which is like runlevel 3 in SystemV.
Where do I find the dependencies in systemd?
