[BUG] setup-ngxblocker won't work properly with custom nginx vhosts location where files are symlinks

[ioweb-gr]

Describe the bug

I'm using a plesk server and wanted to install the blocker. After setting everything up I need to mass update the vhosts configuration files.

Unfortunately when trying this I notice a few issues

On the installation the vhosts files are stored in

/etc/nginx/plesk.conf.d/vhosts

with symlinks like this

like this lrwxrwxrwx 1 root root 47 May 29 09:21 ioweb.gr.conf -> /var/www/vhosts/system/ioweb.gr/conf/nginx.conf

Moreover they have multiple server {} blocks declared

To Reproduce

I run

setup-ngxblocker -x -d -v /etc/nginx/plesk.conf.d/vhosts/ -e .conf

And the script did the following

1. It converted the symlinks to actual files. It should have modified the files without altering the symlinks
2. It added the directive only on the last server block

Expected behavior

The directive include /etc/nginx/bots.d/blockbots.conf is included in all server blocks on the original files and not break the symlinks
