Hello,
I’m new to NixOS. I have installed fail2ban on my NixOS system.
How can I create a new etc/fail2ban/filter.d/<my-filter-name>
text file with my own content within my configuration.nix
?
Bonus question: where is that documented?

Nix packages are supposed to be configured [1] to pick their
configuration data from /etc
, not the package directory, which is
immutable anyway.
You can use
environment.etc."fail2ban/filter.d/<my-filter-name>".source
in your
configuration.nix
to create the file in /etc
:
https://nixos.org/nixos/options.html#environment.etc
[1]: Sometimes, the packagers miss this and the package only tries to
find the configuration in ${pkg}/etc
. This is a bug and needs to be
reported.
You mean .text
instead of .source
right?
Yeah, you can use .text
if you want to embed it directly into you configuration.nix
