[systemd-devel] test-dhcp-client failing in mock builds

[Zbigniew Jędrzejewski-Szmek]

Hi,

I was trying to enable tests in the %check part of systemd rpm.
Something strange happens which causes test-dhcp-client when building
in mock:

FAIL: test-dhcp-client

As you can see, stopping fails with EPERM. But when I run it by hand
in the same build root, it works fine. Could this be some kind of race?
I don't know this part of the code at all, so I'm at loss here.

For comparison, the same binary executed by hand:

# ./test-dhcp-client
