A colleague actually figured this out.
There is an entry in /lib/modprobe.d/systemd.conf that seems to
override any other user configurations applied.
options dummy numdummies=0
...needs to be removed from this file (or at least modified, but since
my configuration already lays that down in /etc
Requirement is a very strong word , but you should consider using it and here
is a short demo why:
- By default, RHEL uses NetworkManager to configure and manage network
connections, and the /usr/sbin/ifup and /usr/sbin/ifdown scripts use
NetworkManager to process ifcfg files in the /etc/syscon

IIRC the old style network scripts will go awa
As far as what dummy interfaces are used for, they're basically
loopbacks that allow for some better network management/flexibility
(by separating it from the actual system loopback).

No. Network Manager is always disabled on our builds since at least
Cent5 days. The network stack has always been able to be managed
properly without relying on Network Manager. Is that now an absolute
requirement? It never has been prior.

Have you tried with Network Manager , after all this is the thing that manages
all networks:
[root@system ~]# nmcli connection add con-name dummy0 ifname dummy0 type dummy
Connection 'dummy0' (9fdd74fa-c143-4991-9bac-0e542704ac89) successfully added.
[root@system ~]# reboot
Shared connection
Have you tried to use NetworkManager ?
After all ,anything network related should be done by it.
[root@system ~]# nmcli connection add con-name dummy0 ifname dummy0 type dummy
Connection 'dummy0' (9fdd74fa-c143-4991-9bac-0e542704ac89) successfully added.
[root@system ~]# reboot
Shared connectio
Anyone have any ideas? It's rather annoying that I can't get these to
persist across reboots without using some kind of helper script.
