From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

NixOS - edit system files (lemmy.ml)

Hello,

I'm experiencing with NixOS and would like to know what would be the nicest way to add a specific line to a system file.

As an example, how would you configure NixOS so the line
auth sufficient pam_fprintd.so
is added to the /etc/pam.d/doas file? As a bonus, it would be nice to know how to change an option (and not add an entire line) to a system file for which there is no NixOS default extraConfig/extraRules support for.

This would allow me to add this line or not depending on the machine NixOS will be installed on.

Thanks in advance for your suggestions.

No, that one is in the search as well. It's a normal option. https://search.nixos.org/options?show=security.pam.services.%3Cname%3E.fprintAuth

What isn't and also isn't in the manual is the rules options. Those are all internal.
