It defines ./. as the content to be copied into /etc/nixos-orig. This 
means that everything in the same directory as the file where this is 
defined will be copied to the store and made available in 
/etc/nixos-orig. Be careful not to secret files and private keys 
potentially located there, as nixos-rebuild often runs as root and 
will happily copy them to the store.

Re: [Nix-dev] [Help] Accidentally removed configuration.nix

2017-04-10 Thread Layus 

This is pure genious !
Simple and yet powerful. Thanks for sharing :-).
It can be customized with filterSource and such if you want more control.

However, it does not track modifications to nixpkgs.
I have a bad habit of building NixOS from dirty nixpkgs repos to test my 
various fixes.

Any idea to handle that ?

This issue is likely to trip most newcomers. Maybe nixos-install should
create a git repo in /etc/nixos by default. And then "nixos build"
automatically commit on invocation.

Re: [Nix-dev] [Help] Accidentally removed configuration.nix

2017-04-09 Thread Ryan Trinkle 
Jeaye,

I totally agree!  One really interesting approach to this that I've seen is
the 'pass' password manager, which can automatically handle the use of git
for passwords.  I wonder if it would be feasible to do this for nixos as
well, so that beginners (who might not be familiar with git) would
automatically be doing "the right" (or at least "a reasonable") thing
without needing to learn about it.

I know you've sorted this out now, but I think it's worthwhile to mention that 
one of the benefits of having a text-based, declarative configuration for your 
OS is that you can very easily track it in git. NixOS will handle reverts for 
you, on an OS level, and git can handle them for you on a configuration level.

If you don't want to host the configurations publicly, on Github or similar, 
you could do so privately, on Bitbucket or similar.

Best of luck.

implementation bitrotting in a PR.


But I have an idea to end this ;-). Coming soon :-D.

If you want a correct system.copySystemConfiguration, you really

It allows you to snapshot all the sources of a nix derivation, not

I tested it back then, and it worked pretty well.

If you have enabled system.copySystemConfiguration option, you can find
your config at /var/run/current-system/configuration.nix

Though, the option is disabled by default, so it's unlikely that will help
you this time :(

Also, it only copies the main configuration file and not any included
files.

Alexey

Re: [Nix-dev] [Help] Accidentally removed configuration.nix

2017-04-06 Thread Ryan Trinkle 
Hi Vince,

I do happen to know why it's set to false by default!  I sent a PR to
change it to true a while back, and got some good explanations for why
that's a bad idea here: https://github.com/NixOS/nixpkgs/pull/16922

However, I'm now wondering if it might make sense to add
"system.copySystemConfiguration" to nixos-generate-config's default output;
I added a comment to that PR explaining the idea.


Best,
Ryan
