XDG Base Directory is a standard for locations for storing various
files. Nix has a few files which seem to fit in the standard, but
currently use a custom location directly in the user's ~, polluting
it:
- ~/.nix-profile
- ~/.nix-defexpr
- ~/.nix-channels
This commit adds a config option (use-xdg-base-directories) to follow
the XDG spec and instead use the following locations:
- $XDG_STATE_HOME/nix/profile
- $XDG_STATE_HOME/nix/defexpr
- $XDG_STATE_HOME/nix/channels
If $XDG_STATE_HOME is not set, it is assumed to be ~/.local/state.

Before this patch, installing Nix using the Fish shell did not
work because Fish wasn't configured to add Nix to the PATH. Some
options in #1512 offered workarounds, but they typically involve
extra plugins or packages.
This patch adds native, out-of-the-box support for the Fish shell.
Note that Fish supports a `conf.d` directory, which is intended
for exactly use cases like this: software projects distributing
shell snippets. This patch takes advantage of it. The installer
doesn't append any Nix loader behavior to any Fish config file.
Because of that, the uninstall process is smooth and a reinstall
obliterates the existing nix.fish files that we place instead of
bothering the user with a backup / manual removal.
Both single-user and multi-user cases are covered. It has been
tested on Ubuntu, and a Mac with MacPorts, homebrew, and the
Fish installer pkg.
Closes#1512

ShellCheck correctly warns:
In scripts/install-nix-from-closure.sh line 218:
echo -e "\nif [ -e $p ]; then . $p; fi # added by Nix installer" >> "$fn"
^-- SC3037: In POSIX sh, echo flags are undefined.
In scripts/install-nix-from-closure.sh line 229:
echo -e "\nif [ -e $p ]; then . $p; fi # added by Nix installer" >> "$fn"
^-- SC3037: In POSIX sh, echo flags are undefined.
Indeed, this actually breaks on Ubuntu where /bin/sh is dash.
Fixes#5458.

While the progress dots during the copying of the store work fine on a
normal terminal, those look pretty off if the script is run inside a
provisioning script of e.g. `vagrant` or `packer` where `stderr` and
`stdout` are captured:
default: .
default: ..
default: .
default: .
default: .
To work around this, the script checks with `-t 0` if it's
running on an actual terminal and doesn't show the progress if that's not
the case.
- xpath -> xmllint: xpath's cli interface changed in Big Sur
rather than add conditional logic for picking the correct
syntax for xpath, I'm changing to xmllint --xpath, which
appears to be consistent across versions I've tested...
- /plist/dict/key[text()='Writable']/following-sibling::true[1]
doesn't do quite what's expected. It was written to try to
select a <true /> node paired with the Writable key, but it
will also select the *next* <true /> node that appears even
if it was paired with another key.
- I think there's also a logic bug in the conditionals here.
I'm not sure anyone ever actuall saw it, thanks to the xpath
bug, though. With the xpath fix, this conditional passes if /nix
does not exist, / IS writable, and the version is Catalina+.
I think it meant to test for /nix does not exist, / is NOT
writable, and the version is Catalina+. I reworked this lightly
to make it a little clearer at the code level.
This should handle installation scenarios we can handle with
anything resembling confidence. Goal is approximating the existing
setup--not enforcing a best-practice...
Approaches (+ installer-handled, - manual) and configs each covers:
+ no change needed; /nix OK on boot volume:
All pre-Catalina (regardless of T2 or FileVault use)
+ create new unencrypted volume:
Catalina, pre-T2, no FileVault
+ create new encrypted-at-rest volume:
Catalina, pre-T2, FileVault
Catalina, T2, no FileVault
- require user to pre-create encrypted volume
Catalina, T2, FileVault
The default login shell for users on macOS 10.15 changed from bash to
zsh. So while generally nonstandard we need to configure it to make nix
function out of the box on macOS.
Starting macOS 10.15 /nix can't be creasted directly anymore due to the
readonly filesystem, but synthetic.conf was introduced to enable
creating mountpoints or symlinks for special usecases like package
managers.
Instead, print a message about what happened and tell the user what can
be done (run "[sudo -i] nix-channel --update nixpkgs" again at a later
time). This change allows installing Nix when you're offline.
Since the multi-user installer is so verbose, the message isn't printed
until the end.
Fixes issue #2650 ("installation without internet connection").
By passing --daemon or --no-daemon, the installer can be forced to
select one or the other installation options, despite what the
automatic detection can provide.
This commit can be backported to 2.0-maintenance because it explicitly
turns off the daemon installation for Linux under systemd.
- darwin installer: delete hardware report, not necessary
- moves os-specific code from the darwin installer to to `poly_*`
functions
- adds profile.d support to the profile targets, which automatically
handles many distros which don't have a /etc/bashrc but do have an
/etc/profile.d
- /bin/bash -> /usr/bin/env bash
- document why each excluded shellcheck check is excluded
- rename the multi-user to Daemon-based
