I see this https://github.com/piku/piku/blob/master/docs/ubuntu-18.04-bionic.md has the simplified version:
sudo ln /home/$PAAS_USERNAME/.piku/uwsgi/uwsgi.ini /etc/uwsgi/apps-enabled/piku.ini
sudo systemctl restart uwsgi
from piku.

The simplified version is the way to go. Feel free to revise the merged docs and do another PR.

Looks like this is enough for uwsgi setup:
ln -s /home/$PAAS_USERNAME/.piku/uwsgi/uwsgi.ini /etc/uwsgi.d/piku.ini
Per my understanding, these 2 files
https://raw.githubusercontent.com/piku/piku/master/uwsgi-piku.service
https://raw.githubusercontent.com/piku/piku/master/uwsgi-piku.dist
are just needed to reload uwsgi on config changes.
uwsgi does this already. Quoting from https://uwsgi-docs.readthedocs.io/en/latest/Emperor.html
Whenever an imperial monitor detects a new configuration file, a new uWSGI instance will be spawned with that configuration.
Whenever a configuration file is modified (its modification time changed, so touch --no-dereference may be your friend), the corresponding app will be reloaded.
Whenever a config file is removed, the corresponding app will be stopped.

Yes, but linking alone increases the host attack service if I can get inside the piku user or one of its apps, so copying is the way to go here. Again, AFAICR the extra service was a way to avoid breaking the original one in earlier Ubuntu releases, not just to have it force-reload.

That makes sense.
I copied linking step from existing https://github.com/piku/piku/blob/master/docs/INSTALL-ubuntu-18.04-bionic.md
(and added -s to work on different filesystems)
Should that ln be replaced with cp in INSTALLs ?

Are those still needed? It seems only this would do the job:
sudo cp /home/$PAAS_USERNAME/.piku/uwsgi/uwsgi.ini /etc/uwsgi/apps-enabled/piku.ini
from piku.

Back to the request:
Per my understanding, these 2 files
https://raw.githubusercontent.com/piku/piku/master/uwsgi-piku.service
https://raw.githubusercontent.com/piku/piku/master/uwsgi-piku.dist
are just needed to reload uwsgi on config changes.

Whenever a configuration file is modified (its modification time changed, so touch --no-dereference may be your friend), the corresponding app will be reloaded.
Whenever a config file is removed, the corresponding app will be stopped.
I've tested this with piku config:set A=b and `piku logs' shows the app being restarted.
Would you please remove to 2 files, to avoid confusion with new setups?
