I canβt understand why the systemd process can write more than 1 GB of data to disk in a day.
I noticed that if open and close google-chrome, then the record grows from 20 to 40 mb

have you checked in log journals ?
Yes, I checked it. Didnβt find anything that pointed to a record.
Did :
sudo fatrace -f W
sudo strace -p PID
sudo lsof -p PID
sudo strace -yy -e trace=open,openat,close,write -f -p PID
systemd process PID
Same way didnβt find anything that pointed to a record.
While I was sitting on the forum and closed google-chrome, the entry increased by 500 mb
Apparently no one has come across such a thing.
check if there any debug line in config systemd that do writes to the disk ( or somewhere )
This is a guess with the following assumption: All processes are started from the initial systemd PID 1
The application that does the accounting measures the total for each proces and child processes.
The measurement you see is the total written from one of the running process and child processes.
For comparison: my gnome system systemd process has written 4,4GB today and is up 8 hours, some browsing, some gaming, some reading, some administrative chores.

I compared how much chrome wrote, the same amount was added to the total record for systemd.
Hey, this is helpful stuff
