Description Konstantin A Lepikhov (L.A. Kostis) 2016-05-06 17:33:27 MSK
1. Описание проблемы

Просто взял и поставил unbound из Сизифа, ничего в конфиге не менял. Потом погасил bind и попробовал запустить сервис unbound:

root@lks ~]# service bind stop
Stopping named service: [ DONE ]

[root@lks ~]# service unbound start
Update root anchor: ... no need update /var/lib/unbound/root.key[PASSED]
Checking unbound configuration:[ DONE ]
Starting unbound service: [ DONE ]

[root@lks ~]# ping www.ru

После изменения владельца на root:_unbound для /var/lib/unbound все стало работать как надо.

Предполагаю, что нужно chroot'титься не в /lib/unbound, а в /lib/unbound/keys.d или куда-нибудь отдельно.

# fgrep -r chroot /etc/unbound
/etc/unbound/unbound.conf:      # if given, a chroot(2) is done to the given directory.
/etc/unbound/unbound.conf:      # i.e. you can chroot to the working directory, for example,
/etc/unbound/unbound.conf:      # If chroot is enabled, you should pass the configfile (from the
/etc/unbound/unbound.conf:      # chroot has been performed the now defunct portion of the config
/etc/unbound/unbound.conf:      # The pid file can be absolute and outside of the chroot, it is
/etc/unbound/unbound.conf:      # written just prior to performing the chroot and dropping permissions.
/etc/unbound/unbound.conf:      # If you give "" no chroot is performed. The path must not end in a /.
/etc/unbound/unbound.conf:      # chroot: "/var/lib/unbound"

Версия unbound:

# rpm -q unbound

То было просто обновление.


А вообще ошибка у меня не воспроизводится (проверял в контейнере, взял архив p7 после его обновил на сизиф)
