This adds an explicit unmount of the store volume to avoid cases
where the installer can hang in await_volume when:
- the user already has a store volume
- that volume is already mounted somewhere other than /nix
- they do not take a path through the installer that results in an
explicit unmount (as both removing and encrypting the volume
would do)
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.

Indeed, this actually breaks on Ubuntu where /bin/sh is dash.

As reported in #5198, volume creation can fail with a permission error
for some macOS users (probably secondary user accounts?) Sudo appears
to be sufficient to avoid this.
While I'm here, I also updated the sudo invocation added in 079bde2ae
to use the _sudo explanation wrapper.
This reverts commit 909d8cb293.
This messes up PATH priority since /etc/profile gets sourced AFTER
/etc/zshenv and it sets the system paths so
$HOME/.nix-profile/bin:/nix/var/nix/profiles/default/bin is behind
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin. See discussion in
https://github.com/NixOS/nix/issues/4169.
When commit 233b61d3d6 (#4224) renamed
@binaryTarball_${system}@ to @tarballHash_${system}@, it updated this
reference for every platform except Darwin.arm64.

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.
gnu-config standardized on aarch64 for machine name so host_cpu part
of $system will always be aarch64. That means system will be
aarch64-darwin too.
uname however could report either “aarch64” (if gnu coreutils) or
“arm64” (if apple’s uname). We should support both for compatiblity
here.
NIX_PROFILES is space separated list of directories, and passing it into
for as is is considered to be 1-element list with the whole string. With
shwordsplit option Zsh emulates other shells in this regard ans
implicitely splits unquoted strings into words.
Fixes#4167.
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.
Some of the changes in #3788 to support non-systemd Nix installs
don't appear to be aware that the darwin installer exists, which
resulted in some skipped steps and inappropriate instructions.
As mentioned in previous commit, Big Sur changes the syntax for the
xpath command slightly.
In the process of testing out replacements for these, I noticed a few
small simplification wins.
- 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.
