[nix] nix-2.2.1_2 fails to initialize after fresh install

[alixinne]

System

• xuname: Void 4.19.28_2 x86_64 GenuineIntel uptodate rrFFF
• package: nix-2.2.1_2

Expected behavior

After installing the package and opening a new shell (so /etc/profile/nix.sh is sourced), running nix-* commands should work as expected, e.g. nix-channel --update.

Actual behavior

We encounter the error described in NixOS/nix#2673:

$ nix-channel --update
unpacking channels...
error: while setting up the build environment: getting attributes of path '': No such file or directory
error: program '/usr/bin/nix-env' failed with exit code 1

Proposed fix

As in NixOS/nix#2673 we should add --with-sandbox-shell=/bin/sh to ./configure arguments at build time.

void-packages/srcpkgs/nix/template

Line 7 in cfe41fc

configure_args="--localstatedir=/nix/var"

Workaround

Set sandbox-paths = /bin/sh=/bin/sh in /etc/nix/nix.conf
