Repository with the latest patch: https://github.com/0mp/freebsd-ports-nix

Test Plan

Apply the patch.

Run the following commands:

host# poudriere testport -j 120a -o sysutils/nix -I
host# jexec 120a-default-n env -i TERM=$TERM /usr/bin/login -fp root
jail# make -C /usr/ports/sysutils/nix test

At the moment it fails in the configure phase as it cannot find libcrypto.

Interestingly, if we add autoreconf to USES then it cannot find OPENSSL. It probably has something to do with the bootstrap.sh script mentioned in the manual here: https://nixos.org/nix/manual/#sec-building-source

[0mp]

Fix further configure errors.

Thanks to @ndowens_yahoo.com for showing me how to start patching configure.ac.

[0mp]

Work a little bit more on the nix port.

Does this *really* need 10 different UIDs ?
UIDs are scarce, and with a very limited number, they should probably not be abused like that.

This part of the manual says that you need X nixbld users if you want to build X packages concurrently. I'd say that we might want to just provide a script wrapper for creating users or add a note to pkg-message. The number of users depends heavily on user's use case...

BTW I've added some references to the description of this differential revision.

I think this should be left to the operator to create, as the number of packages you can build at the same time depends on your CPU, and can range from 1 to a hundred.

Maybe provide a script to create the users and add a note to it in pkg-message.

I've created a repository to coordinate work over this patch: https://github.com/0mp/freebsd-ports-nix

Why is a package manager needed, if we already have a package manager (pkg)?

A lot of people would like to see Nix running on FreeBSD, it seems to be a nice piece of technology and managing packages is only a small subset of its features.

managing packages is only a small subset of its features

The port description is incomplete then. -)

Hmm, sure. I could probably be improved a little bit.

This is not the latest patch BTW. See the description on the top of this website for a link to the repo.

As this surfaces, record my request for changes.

Please do not use static users and groups, provide a script to create the number of users/groups the user will need.

I've done it already in the version of the port I keep on GitHub at the moment. Thanks for the reminder :)

Can we add 1 user first and then later add more if this would be needed?

The latest patch on GitHub (https://github.com/0mp/freebsd-ports-nix) just creates a group and then offers a script to create a desired number of users.

Is this version usable? If yes, can you commit it?

I think its time to commit this port, so I'd like to ask you for a review. Thanks!
