While trying to figure out how `nix-env`/`nix profile` work I had a hard
time understand how man pages were being installed.
Took me quite some time to figure this out, thought it might be useful
to others too!
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.
Same purpose as de9efa3b79af7886fcf2a67b6ce97d4f96a57421
For some unclear reason, we get occasional reports from people who do
not have /usr/sbin on their PATH that the installer fails. It's a
standard part of the PATH, so I have no clue what they're doing to
remove it--but it's also fairly cheap to avoid.
Add a regular github action that will check the status of the latest
hydra evaluation.
Things aren’t ideal right now because this job will only notify “the
user who last modified the cron syntax in the workflow file” (so myself
atm). But at least that’ll give a notification for failing hydra jobs
We had a macOS user present in Matrix with some confusion because the
lack of a clear task statement here made them think the error meant
that a problem had occurred during the preceding task in a macOS
install: "Fixing any leftover Nix volume state"
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.
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.

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.
