How can I override glibc in nix-shell and use eglibc, for instance? Are there
any examples? Do I need to override stdenv for that? Overriding the attributes
of glibc (version and sha) directly doesn't seem to work. Could anyone provide
an example?

Not to turn this into a flame war, but there were discussions in the past
whether Nix should have been a DSL embedded in, say, Haskell. IIRC, you felt
okay about it being a standalone DSL, do you still feel the same way?
P.S. Yes, I know about Guix, but it's written in (a uni-typed) Scheme.

TL;DR: I'd like to change '~/.ssh/authorized_keys' via ssh-copy-id. The
file gets changed, but the changes have no effect on the running system.
In 'configuration.nix', I already have 'openssh.authorizedKeys.keys', so I've

I'd like to enable cscope and clipboard support in vim by editing only the
configuration.nix file. If I understand the NixOS manual correctly, it should
look like this:

Is there a way to build packages from Stackage? It'd be cool to have a
separate namespace for that, so I could refer to a package as
stackagePackages.something.
That's the only relevant post I've found:

Stdenv should put ld.gold on PATH, so then it can be used just as

Looking at the source (nixos/modules/services/audio/mpd.nix), it looks
like the mpd service is designed to run as the mpd user. If you are
willing to go with that design, I guess you should not set
services.mpd.dataDir, and make sure the mpd user has read access to
your music directory. (It

Both directories exist.

How do I automatically lock the screen in NixOS? I've installed

It's a problem because these lines in configuration.nix:

Just for what it's worth, I have in the past indexed everything, but it causes
far too much noise in the search output. This is why the hoogle-local
expression takes the approach of asking for a list of 'packages' to indicate
what should be indexed.
Well, it's certainly better than nothing.
Has anyone tried that? Most of the guides suggest you to run the
following command, which should download the necessary databases, but it
fails for me.

I actually think we should *remove* meta.license entirely (because it doesn't

replace it with attributes that have operational meaning:

Nope.

I’m trying to configure NixOS with LUKS over LVM as described in [1].
After partitioning the disk (see ‘partition-table.sfdisk’), I did the

I have committed a patch recently that fix building of cabal-install

The way to go is to create a separate profile for every version of GHC

Ah, right, you'll need something like nix-env -iA
