Run the activation script in its original nix-store location so that
Bash error messages show the real script location instead of 'wrkdir',
which gets deleted right after the script exits.
Because 'set -e' has no effect on commands that run in an if condition,
the script was always exiting with no error when 'doBuild' failed.
As a bonus, $wrkdir is now always removed after building.
We must only follow the symbolic link once (i.e., not use the `-e`
option) since otherwise the pattern will not match when
`home.file.xyz.source` is a directory.
If the `home-manager` module is enabled then check if the
`home-manager` package is installed using `nix-env -i` and if so then
it is automatically uninstalled before the new package environment,
which includes home-manager, is installed.
This module is a module to install and configure the home-manager
tool. By managing the home-manager tool through the Home Manager
module system it will be installed/updated on configuration
activation.
Problem
-------
We resolve symlinks from inside `/nix/store/HASH-home-manager-files`
into the nix store as `/nix/store/HASH-DRVNAME` which does not match
the pattern.
This happened to me because I pull in some repos in via `home.file`.
The `home-manager-files` derivation links to the repo's derivation in
the nix store. For example:
let nanorcs = fetchFromGitHub {
owner = "scopatz";
repo = "nanorc";
…
}; in [
{
target = ".nano";
source = nanorcs;
}
{
target = ".nanorc";
source = "${nanorcs}/nanorc";
}
]
Solution
--------
Call `readlink` without `-e` to obtain only the first redirection from
`~` to `/nix/store/HASH-home-manager-files`.
When a file has disappeared between the previous and the next
generations then its symlink in `$HOME` is typically deleted. With
this commit we refuse to delete the path unless we are reasonably
certain it is a symlink into a Home Manager generation.
This commit changes the default path of the Home Manager configuration
file from `~/.nixpkgs/home.nix` to `~/.config/nixpkgs/home.nix`. The
old path is still supported and will be used if the `.config` path
does not exist.
This aligns Home Manager with the preferred configuration directory in
NixOS 17.03.
Fixes#13.
This removes the old argument based method that Home Manager used to
find its modules by a `NIX_PATH` based method. Specifically, this adds
a `home-manager` Nix path prefix that can be overridden much like with
the `nixpkgs` path prefix.
This is a module for managing the GNU info directory for the user
profile. See comments at the top of `modules/programs/info.nix` for
further information.
This commit causes an error to be printed if running under a non-Linux
system when a systemd service, target, or timer is active.
It will also prevent running systemd during activation if running
under a non-Linux system.
In the activation script we expect to use the tools provided by GNU
Core Utilities and GNU Bash. This commit therefore explicitly add
these first in the `PATH` environment variable.
This module generates a `.ssh/config` file. This doesn't embed _all_
options for the ssh client, but the most common ones should be there.
Example usage:
```nix
programs.ssh = {
enable = true;
forwardAgent = true;
controlMaster = "auto";
matchBlocks = [
{
host = "something.blah.edu";
port = 1024;
user = "cleague";
identitiesOnly = true;
}
{
host = "host1 host2 host2.net host2.com";
port = 7422;
hostname = "example.com";
serverAliveInterval = 60;
}
{
host = "lucian";
forwardX11 = true;
forwardX11Trusted = true;
checkHostIP = false;
};
};
};
```
Each entry in `programs.ssh.matchBlocks` must contain a `host` field,
which will be used for the block condition.
This should reduce the risk of overwriting an existing file in the
user's home directory. A file will only be replaced if it is a link
pointing to a home-manager tree inside the Nix store.
If an existing file is detected an error is written indicating the
file's path and the activation will terminate before any mutation
occurs.
Fixes#6
Previously the home files were not linked if the generation hadn't
changed. Unfortunately, this would mean that, if a file link was
removed for some reason it would not be recreated by running a switch
command.
