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.

Hello all, hoping someone can help me out here. I cannot get dummy interfaces on a new Cent8 build to persist across reboots. On Cent7 - this is the process I use: Create Dummies: # cat /etc/modules-load.d/dummy.conf dummy # cat /etc/modprobe.d/dummyopts.conf options dummy numdummies=4 # ip link add dummy0 type dummy ## - repeating a/ ascending dummyN adapters for as many needed # service
