Subject: [PATCH] networkd: rework idle detection logic of networkd
|
|
|
|
This patch makes networkd stay around as long as there is more than just a
|
|
loopback interface around, or the loopback device isn't fully probed yet, or
|
|
the loopback device has a .network file attached.
|
|
|
|
In essence, this means networkd stays around now continously as it should,
|
|
unless it is running in some (container?) environment that really has no
|
|
interface except a loopback device.
|
|
|
|
Fixes #2577.
|
|
|
|
(cherry picked from commit 9dc907f9c93636cb63ca90300fa3b8c03812701f)
