[Nix-dev] add ubuntu support to debootstrap

[Stefan Huchler]

Hi,

I made a ubuntu version of the debootstrap installer, which adds support
to ubuntu releases.

I could upload that "debootstrap-ubuntu" version to github and open a PR
for it.

But I wonder if that makes sense, cause the debootstrap version of
ubuntu comes with the scripts for debian and ubuntu.

So why not just use that version of debootstrap instead of the one from
debian directly?

thats basicly what I did, it installs / runs and works just had to
disable pgp check:

debootstrap-ubuntu --no-check-gpg xenial ubuntu 
I: Retrieving InRelease 
I: Retrieving Packages
....
I: Base system installed successfully.


this is neat especialy because the machinectl pull-tar functionality
doesnt work too, so this is a good method to get systemd-nspawn
compatible build.

Well or is it?

$ sudo systemd-nspawn -b -D ubuntu/
Spawning container ubuntu on /home/black/virt/ubuntu.
Press ^] three times within 1s to kill container.
/etc/localtime does not point into /usr/share/zoneinfo/, not updating container timezone.
Cannot be run in a chroot() environment.
Freezing execution.

Well is nspawn buggy in nixos? that should work as far as I know.

So sorry now thats 2 topics:
1. would it make sense to use the ubuntu-debootstrap version (with the
scripts from ubuntu) or should I make a PR for the ubuntu-version?
2. is systemd-nspawn working?
