Someone could port the change to= ifconfig(8) I made to NetBSD to add the -w and -W flags to wait for the te= ntative and detached flags to clear from the interfaces=2E This can be used= instead of any arbitrary sleep based on the dad count sysctl=2E

I always need for now to remove DA bot= h on the system but also any jails using vnet=2E Is there any external issu= e that could cause this issue?

Any help/hint is welcome :)
