chore(3p/nix): unvendor tvix 0.1 r/4098
Nothing is using this now, and we'll likely never pick this up again,
but we learned a lot in the process.

Every now and then this breaks in some bizarre way on channel bumps
and it's just a waste of time to maintain that.

-<title>Multi-User Mode</title>
-
-<para>To allow a Nix store to be shared safely among multiple users,
-it is important that users are not able to run builders that modify

-builds started by other users.  If they could do so, they could
-install a Trojan horse in some package and compromise the accounts of
-other users.</para>
-
-<para>To prevent this, the Nix store and database are owned by some

-executed under special user accounts (usually named
-<literal>nixbld1</literal>, <literal>nixbld2</literal>, etc.).  When a
-unprivileged user runs a Nix command, actions that operate on the Nix
-store (such as builds) are forwarded to a <emphasis>Nix
-daemon</emphasis> running under the owner of the Nix store/database
-that performs the operation.</para>
-
-<note><para>Multi-user mode has one important limitation: only
-<systemitem class="username">root</systemitem> and a set of trusted
-users specified in <filename>nix.conf</filename> can specify arbitrary
-binary caches. So while unprivileged users may install packages from
-arbitrary Nix expressions, they may not get pre-built

-
-<title>Setting up the build users</title>
-
-<para>The <emphasis>build users</emphasis> are the special UIDs under
-which builds are performed.  They should all be members of the
-<emphasis>build users group</emphasis> <literal>nixbld</literal>.
-This group should have no other members.  The build users should not
-be members of any other group. On Linux, you can create the group and
-users as follows:
-
-<screen>
-$ groupadd -r nixbld
-$ for n in $(seq 1 10); do useradd -c "Nix build user $n" \
-    -d /var/empty -g nixbld -G nixbld -M -N -r -s "$(which nologin)" \
-    nixbld$n; done
-</screen>
-
-This creates 10 build users. There can never be more concurrent builds

-
-<para>To let unprivileged users use the daemon, they should set the

-<title>Security</title>
-
-<para>Nix has two basic security models.  First, it can be used in
-“single-user mode”, which is similar to what most other package
-management tools do: there is a single user (typically <systemitem
-class="username">root</systemitem>) who performs all package
-management operations.  All other users can then use the installed
-packages, but they cannot perform package management operations
-themselves.</para>
-
-<para>Alternatively, you can configure Nix in “multi-user mode”.  In
-this model, all users can perform package management operations — for
-instance, every user can install software without requiring root
-privileges.  Nix ensures that this is secure.  For instance, it’s not
-possible for one user to overwrite a package used by another user with
-a Trojan horse.</para>
