Now I suppose I shouls put that in a systemd script...
Thank you very much.

Did all this.
All my free -th results looked the same.
Could it be it was already there?
Assuming there is an advantage to this, how does one get it going on startup.
I HAD a sysinit script for it at one time, before the new days of systend.
I have decided to use the following script and it seems to work :
git clone https://github.com/Jiab77/systemd-zram
cd systemd-zram
./install.sh
You can the remove systemd-zram directory.
Here you can modify /etc/systemd/zram.conf from 33% to 50 for next
reboot… But it is only to adopt the same policy as Ubuntu, but the
original prefers 33%...
