[pve-devel] [PATCH installer 0/6] fix #5811: add option to retrieve FQDN from DHCP configuration

[Christoph Heiss <c.heiss@proxmox.com>]

Fixes #5811 [0].

Adds a new option to the answer file for specifying to use the
DHCP-provided hostname and domain. For the domain, an additional
fallback/default can be specified, in case the DHCP server only provides
hostnames. The hostname is always required in this mode.

The addition to the answer file format is done in a backwards-compatible
way.

Users can now specify the following to use the DHCP-provided domain:

```
[global]
fqdn.source = "from-dhcp"
```

or additionally with a custom domain:

```
[global.fqdn]
source = "from-dhcp"
domain = "custom.domain.local"
```

Patches #1 through #4 can all be applied independently, #1 & #4 are pure
cleanups.
