[Touch-packages] [Bug 1888391] Re: /etc/dhcp/dhclient-enter-hooks.d/resolved should not run in non-root network namespaces
You' re right. It's provided by isc-dhcp-client. Can' t recall how I
ended up with reporting this against systemd 4 years ago.

/etc/dhcp/dhclient-enter-hooks.d/resolved should not run in non-root
network namespaces

Bug description:
Running dhclient in a (non-root) network namespace on a system with
systemd enabled fails because the hook installed by the systemd
package updates the DNS configuration of the core/root namespace,
instead of simply the /etc/resolv.conf file of that particular network
namespace.
("ip netns add " nicely links /etc/resolv.conf in that namespace
to /etc/netns//resolv.conf if it exists.)
The following patch ensures that this script no longer misbehaves for
this scenario:

I don't think that script is or was part of src:systemd?
