 For the distro of choice I'll pick alpine, for its small footprint and the use
 of OpenRC (nothing against systemd though).

+### Permission
+
+Now comes the part where we should be careful. So far we (or at least I) have
+been setting up everything as root but that is not ideal. We want to restrict as
+much as possibly permission to the processes, it should only see do what it
+meant to. So to minimize the effect of the process we will make it run as a user
+with almost no permission, and for purpose we will create a `www-data` user.
+Quite often that user is already create if not run the following command:
+
+```shell
+adduser www-data --disabled-password
+```
+
+Add `--ingroup www-data` if it complains if the groups exists.
+`--disabled-password` so we don't allow login with password, because it is not
+meant to be logged with.
+
+Once the user is created we need to change the which user the process runs one.
+By default it uses a `nobody` which is a user with no permission except those
+which every other user has. Update the user given in the
+`/etc/php8/php-fpm.d/www.conf` file.
+
+From:
+```shell
+user = nobody
+group = nobody
+```
+
+To:
+```shell
+user = www-data
+group = www-data
+```
+
+If the `php-fpm8` is running restart it:
+
+```shell
+rc-service php-fpm8 restart
+```
+
+At last we need to recursively update the permission of www folder because
+probably it is owned by root.
+
+```shell
+chown -R www-data:www-data /var/www/
+```

+## Debugging
