split the util file
Open, Requires assessmentPublicFEATURE REQUEST


Currently, util contains many things in one file, often unrelated.
A util folder could be created grouping command in logical chunks (command operation, file operation, ...)

Event Timeline

For get_bridge_member_config, ifname_from_config and maceui64 to be able
to be moved into ifconfig.interfaces T2366 needs to be done first,
otherwise functionality will break.

I'm not sure ifname_from_config's place is in ifconfig, as it operates
purely on vyos.config so it should be a utility of that.

The same with maceui64, which can take any mac to generate an eui64. A
search of all uses of it needs to be done, to see if it's always
invoked on the interface, or if it's used in other places as well.

I have worked and provided a patch for T2485 .. It may be the right place to move it in.
