- 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.

Keeping this commit narrow for reviewability, but some of these
conditionals will change in subsequent commits in this PR.
Fixes #3852.

- --no-channel-add didn't have effect on multi-user installation
- some new flags didn't work at all
- document all installer flags

install-multi-user: allow overriding user count
|
|
|
|
|
|
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.

This is commonly the default behavior with -R, but POSIX leaves the
default unspecified.

uses $(id -u -n) when USER is unset, this is needed on some weird
setups in Docker. Fixes #971

installer: update macOS version check to 10.12.2
|
|
install script: don't abort when "nix-channel --update" fails
|
|
the nix-store --init command is a noop apparently
|
|
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").
|
|
Nixpkgs will drop support for <10.12 soon and thus a nix release built
using the 19.03 channel will also require a newer version of macOS.
|
|
|
|
Note: don't backport to 2.0-maintenance
|
|
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

This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There
really is no need for such a massive change...

The current behaviour modifies the first writeable file from amongst
.bash_profile, .bash_login and .profile. So .bash_profile (if it is
writable) would be modified even if a user has already sourced nix.sh
in, say, .profile.
This commit introduces a new environment variable,
NIX_INSTALLER_NO_MODIFY_PROFILE. If this is set during installation,
then the modifications are unconditionally skipped.
This is useful for users who have a manually curated set of dotfiles
that they are porting to a new machine. In such scenarios, nix.sh is
already sourced at a place where the user prefers. Without this
change, the nix installer would insist on modifying .bash_profile if
it exists.
This commit also add documentations for both the current behaviour and
the new override.

This prevents collisions with the "native" OpenSSL, in particular on
OS X.
Fixes #921.

Nix sometimes outputs a warning message like this:
```
directory /nix does not exist; creating it by running ‘?? using sudo
```
... when it really meant to output something that looked like this:
```
directory /nix does not exist; creating it by running 'mkdir -m 0755 /nix && chown gabriel /nix' using sudo
```
The reason why is due to some bizarre behavior in Bash where it will translate anything of the form `$x’` to `??`, leading to the incorrect warning message. I don't know what is the origin of this Bash behavior, but the easiest fix is to just use ASCII quotes instead of unicode quotes.

Verification is slow. Also, we really shouldn't advise users to nuke
their store.
|
|
|
|
Just wasted a couple hours chasing shadows because the nix store got
corrupted and there was no indication of that anywhere.
Since an install is one-time only, might as well verify. Optimization
showed that the copied files aren't read-only; fixed that as well.
Also, use /bin/sh since there's a good chance that this script will be
run on systems without /bin/bash
|
|
|
|
The `set -e` at the top of the script causes the installation to fail to
complete if the shell profile is not writeable. Checking file existence
only is not enough.

is not writable by the user
