PVE 7 GUI does not like ifupdown2 syntax

[gartoffel]

Using ifupdown, the following config used to be valid and correctly displayed in the Proxmox VE 7 webinterface:

auto vlan1120
iface vlan1120 inet static
    vlan-raw-device vmbr2
    address 172.16.0.17/27

Using ifupdown2 there is no need to add inet static any longer. See https://cumulusnetworks.github.io/ifupdown2/ifupdown2/userguide.html#configuration-files for details.

However, when using the following config, the Proxmox VE 7 webinterface shows "unknown" as type and no longer displays CIDR etc.:

auto vlan1120
iface vlan1120
    vlan-raw-device vmbr2
    address 172.16.0.17/27

We do not plan to be 100% parser compatible, and still want to be ifupdown v1 compatible.
In your case, simply add "inet static" an it is displayed correctly.

Okay, good to know that this is considered the official workaround. I'll stick to that for now. Thanks, Dietmar!
