Description Maksim Melnikau 2012-11-17 21:48:23 UTC

It is nice, that systemd-nspawn updates /etc/localtime, but it will be nice, if /etc/resolv.conf also will be updated/copied from "host" if not exists/etc.

Steps to reproduce:
1. ping google.com
2. PING google.com (173.194.71.102) 56(84) bytes of data.
3. systemd-nspawn -D /some/path (where /etc/resolv.conf not exists/old/etc)
4. ping google.com
5. ping: unknown host google.com

P.S. there is nice workaround, if dnsmasq runned on "host", "guest" have working DNS resolving, even without /etc/resolv.conf

This should be fixed in v184. Can you confirm that it works for you?

It still exists in systemd 195, I'm running systemd 195 on host and guest

# systemctl --version
systemd 195

systemd-nspawn -D /media/gsoho -b
# stat /etc/resolv.conf
stat: cannot stat ‘/etc/resolv.conf’: No such file or directory

for the bind mount to work we currently need a stub file in the container, that we can overmount. We could first create an empty stub file i guess, but not sure that would be a good idea...

Fixed in git.
