Travis A. Everett bdb5e03821 install-darwin: dodge bash 3.2 command bug
The script is trying to find chown in a cross-platform-like
way, but there's some sort of deficiency in `command -p` in
the default macOS bash 3.2. It looks like it will just use
whatever PATH is already set, instead of the "default" path.

This attempts to hard-set a PATH via `getconf PATH`. It will
just set an empty PATH if that fails for some reason. A
properly-functioning `command -p` should not care what we
set the PATH to here one way or the other.

Hopefully fixes #5768.

Reword "we"s to "I"s for consistency
This script uses multiple forms of the first-person POV:
1. "We" to refer to the Nix team (1e7c796e66/scripts/install-multi-user.sh (L72))
2. "We" to refer to the combination of the installation script & the user/executor (1e7c796e66/scripts/install-multi-user.sh (L710))
3. "We" to refer to the installation script alone (1e7c796e66/scripts/install-multi-user.sh (L602))
4. "I" to refer to the installation script alone (1e7c796e66/scripts/install-multi-user.sh (L200))

Since I prefer POV 4 to POV 3, this changes all instances of POV 3 to POV 4.

Matthew Bauer 959c2af557 Revert "Use /etc/zshenv instead of /etc/zshrc for profile"
This reverts commit 909d8cb293.

This messes up PATH priority since /etc/profile gets sourced AFTER
/etc/zshenv and it sets the system paths so
$HOME/.nix-profile/bin:/nix/var/nix/profiles/default/bin is behind
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin. See discussion in
https://github.com/NixOS/nix/issues/4169.

Travis A. Everett c40bad4151 create missing profile files to fix zsh envvars
Env vars for ZSH were moved from /etc/zshrc to /etc/zshenv in #3608
to address an issue with zshrc getting clobbered by OS updates, but
/etc/zshenv doesn't exist by default--so *nothing* would get set up
for zsh users unless they already happened to have /etc/zshenv.

Creating these files if they don't exist. Also cut separate creation
of profile.d/nix.sh, which isn't needed now.

Greg Price 7313aa267b installer: Fix terminal colors.
The install-multi-user script uses blue, green, and red colors, as
well as bold and underline, to add helpful formatting that helps
structure its rather voluminous output.

Unfortunately, the terminal escape sequences it uses are not quite
well-formed.  The relevant information is all there, just obscured
by some extra noise, a leading parameter `38`.  Empirically, the
result is:

 * On macOS, in both Terminal.app and iTerm2, the spurious `38` is
   ignored, the rest of the escape sequence is applied, and the colors
   show up as intended.

 * On Linux, in at least gnome-terminal and xterm, the spurious `38`
   and the next parameter after it are ignored, and what's left is
   applied.  So in the sequence `38;4;32`, the 4 (underline) is
   ignored but the 32 (green) takes effect; in a more typical sequence
   like `38;34`, the 34 (blue) is ignored and nothing happens.

These codes are all unchanged since this script's origins as a
Darwin-only script -- so the fact that they work fine in common macOS
terminals goes some way to explain how the bug arose.

Happily, we can make the colors work as intended by just deleting the
extra `38;`.  Tested in all four terminals mentioned above; the new
codes work correctly on all of them, and on the two macOS terminals
they work exactly the same as before.

---

In a bit more technical detail -- perhaps more than anyone, me
included, ever wanted to know, but now that I've gone and learned it
I'll write it down anyway :) -- here's what's happening in these codes:

An ECMA-48 "control sequence" begins with `\033[` aka "CSI", contains
any number of parameters as semicolon-separated decimal numbers (plus
sometimes other wrinkles), and ends with a byte from 0x40..0x7e.  In
our case, with `m` aka "SGR", "Select Graphic Rendition".

An SGR control sequence `\033[...m` sets colors, fonts, text styles,
etc.  In particular a parameter `31` means red, `32` green, `34` blue,
`4` underline, and `0` means reset to normal.  Those are all we use.

There is also a `38`.  This is used for setting colors too... but it
needs arguments.  `38;5;nn` is color nn from a 256-color palette, and
`38;2;rr;gg;bb` has the given RGB values.

There is no meaning defined for `38;1` or `38;34` etc.  On seeing a
parameter `38` followed by an unrecognized argument for it, apparently
some implementations (as seen on macOS) discard only the `38` and
others (as seen on Linux) discard the argument too before resuming.

Greg Price 26851dd2c2 installer: Set files read-only when copying into store
After installing Nix, I found that all the files and directories
initially copied into the store were writable, with mode 644 or 755:

  drwxr-xr-x 9 root root 4096 Dec 31  1969 /nix/store/ddmmzn4ggz1f66lwxjy64n89864yj9w9-nix-2.3.3

The reason is that that's how they were in the unpacked tarball, and
the install-multi-user script used `rsync -p` without doing anything
else to affect the permissions.

The plain `install` script for a single-user install takes care to
do a `chmod -R a-w` on each store path copied.  We could do the same
here with one more command; or we can pass `--chmod` to rsync, to
have it write the files with the desired modes in the first place.

Tested the new `rsync` command on both a Linux machine with a
reasonably-modern rsync (3.1.3) and a Mac with its default, ancient,
rsync 2.6.9, and it works as expected on both.  Thankfully the latter
is just new enough to have `--chmod`, which dates to rsync 2.6.7.

Matthew Bauer d4e51aac08 Make preexisting Nix install a warning, not a failure
In the multi-user install script, we originally made sure no previous
references to Nix existed. This prevented any previous installs from
contaminating the new install. However, some users need the ability to
repair their existing Nix installation without uninstalling all
references to Nix. This change allows users with existing Nix
installations to use the installer, while still outputing a warning
message on the dangers of this. As a result, the multi-user install
script work much more like the single-user install script has worked
in the past.

This is a requirement for macOS Catalina users now that
/Library/LaunchDaemons/org.nixos.nix-daemon.plisg is not managed by
the Nix store. If there is ever a change to the .plist, all users will
need to rerun this install script to get the new changes. Otherwise,
changes to the launch daemon will require manual interventions.

Matthew Bauer 0463d5e36f Allow empty /nix directory in multi-user installer
With macOS catalina, we can no longer modify the root system
volume (#2925). macOS provides a system configuration file in
synthetic.conf(5) to create empty root directories. This can be used
to mount /nix to a separate volume. As a result, this directory will
need to already exist prior to installation. Instead, check for
/nix/store and /nix/var for a live Nix installation.

Bjørn Forsman 07d9981f34 install-multi-user: remove unneeded settings from nix.conf
Hardcoding the "max-jobs" and "cores" settings in nix.conf at install

me.

Bjørn Forsman dbe4c043d7 install-multi-user: reduce max-jobs from 32 to 1
Having max-jobs = 32 ($NIX_USER_COUNT is hardcoded to that value) may
severely overload the machine. The nix.conf(5) manual page says max-jobs
defaults to 1, so let's use that value.

NOTE: Both max-jobs and cores are now being set to their default value,
so they can be removed alltogether.

scripts: remove default 'sandbox = false' from multi-user installer
Sandboxing is now enabled by default on Linux, but is still disabled on
macOS. However, the installer always turned it off to ensure consistent
behavior.

Remove this default configuration, so we fall back to the default
platform-specific value.

Bjørn Forsman b9567aa8b6 install script: don't abort when "nix-channel --update" fails
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").
