Description Michal Kubeček 2023-03-20 14:23:59 UTC

After an upgrade from Leap 15.4 to (beta) 15.5, then named daemon (bind)
fails to start with the following error:

> named.service: Failed to set up mount namespacing: /run/systemd/unit-root/var/lib/samba/bind-dns: No such file or directory

While searching for the errror, I found

  https://forums.opensuse.org/t/bind-broken-after-zypper-dup/144767/2

The path in question is in

  /usr/lib/systemd/system/named.service.d/26-samba-dlz.conf

which belongs to samba-ad-dc package. Based on the suggestion from the
forum, I tried to shadow this file with /etc/../26-samba-dlz.conf where
I prefixed the path with "**-**". This seemed to work well but today bind
failed to start again, this time with

> /etc/systemd/system/named.service.d/26-samba-dlz.conf:2: ReadWritePaths= path is not absolute, ignoring: **-**/var/lib/samba/bind-dns

As I'm not familiar with the way systemd handles mount namespaces and
I do not really need or want Samba AD or anything related to it, I tried
to uninstall the samba-ad-dc package; now named starts without any issue.

Will be fixed by next samba-ad-dc update.
