このVagrantfileですべてが動くことを確認できたので【解決】としました。

どうやらFreeBSDにおけるsudo
の実装が内包しているバグだった模様で、公式が「数日内にバグフィックス出すよ」と言っている。とりあえず全裸待機。

==> default: Importing base box 'freebsd/FreeBSD-10.4-STABLE'...
No base MAC address was specified. This is required for the NAT networking
to work properly (and hence port forwarding, SSH, etc.). Specifying this
MAC address is typically up to the box and box maintainer. Please contact
the relevant person to solve this issue.
ふぇぇ
No base MAC address was specified.

って、echoが失敗してるとでも言うのかお前は。ためしに、
% vagrant ssh --command "echo hgoeeee"

Vagrantのログは、providerがVirtualBoxの場合(VirtualBoxのインストールディレクトリにもよるとは思うけれど)、
~/VirtualBox VMs/vagrant-freebsd-test_default_1509154848753_31244/Logs
にあるっぽい。
他には、
% vagrant destroy -f && vagrant up --debug
で得られるものもある。で、それっぽいエラー箇所抜粋↓

ふむ。
sudoerではないprovisionの実行は成功
ためしに、sudo=falseとしてみる。Vagrantfileで、
vb.customize ["modifyvm", :id, "--nictype2", "virtio"]
end
- config.vm.provision "shell", inline: "echo hello"
+ config.vm.provision "shell", inline: "echo hello", privileged: false
end
そんでふたたび、
% vagrant destroy -f && vagrant up --debug
とすると、
ProvisionにおけるユーザのPrivilegeの問題であることが切り分けられた。
provisionにおけるユーザのsudoについて
前述の
をちゃんと読む
Seems like sudo will segfault on official FreeBSD STABLE (but not RELEASE) Vagrant boxes if a hostname isn't set. Problem is Vagrant uses sudo to set any hostname specified in the Vagrantfile or run any shell commands.
Setting it manually worked for me:
% vagrant ssh
vagrant@:~ % su
root@:/home/vagrant # sysrc hostname=myhost.local (modifies rc.conf)
root@:/home/vagrant # halt -p
% vagrant up --provision
うーん、動いたけど、vagrant ssh
してる時点でプロビジョニングツールとしてどうなんだという感じ。

ほんまかいな。-RELEASE
使ったろ。
Vagrant.configure("2") do |config|

+ config.vm.box = "freebsd/FreeBSD-10.4-RELEASE"
config.ssh.shell = "sh"
config.vm.base_mac = "080027D14C66"
で、

ふつうにSegmentation fault出るやん。一応検証のため、
% vagrant ssh
vagrant@:~ % su
root@:/home/vagrant # sysrc hostname=testtest.local
root@:/home/vagrant # halt -p
Connection to 127.0.0.1 closed by remote host.

% vagrant up --provision
んなぁ〜動くなぁ〜。
Vagrantfileによるhostnameの指定は可能か?
config.vm.hostname - The hostname the machine should have. Defaults to nil. If nil, Vagrant will not manage the hostname. If set to a string, the hostname will be set on boot.
いけるっぽいぞ。ためしに、Vagrantfileを、
Vagrant.configure("2") do |config|
config.vm.guest = :freebsd
config.vm.synced_folder ".", "/vagrant", id: "vagrant-root", disabled: true
config.vm.box = "freebsd/FreeBSD-10.4-RELEASE"
config.ssh.shell = "sh"
config.vm.base_mac = "080027D14C66"
+
+ config.vm.hostname = "testtest.local"
+
としてみるものの、
hostnameを実行しようとするとき、同様にSegmentation faultが出ている。
ここまでの結論
- sudoしようとするときにSegmentation faultになる
- sshしてhostnameを設定すると解決する
- 再現可能
