[pve-devel] [PATCH docs v2 2/3] network: adapt apply config section to PVE 7

[Aaron Lauterer <a.lauterer@proxmox.com>]

ifupdown2 is now installed by default, we can therefore omit the whole
installation part except a small note for people who installed PVE on
top of Debian.

also mention the CLI variant for users who like to edit the network
config directly or are using some config management tools

 Reboot Node to apply
 ^^^^^^^^^^^^^^^^^^^^
 
-With the default installed `ifupdown` network managing package you need to
-reboot to commit any pending network changes. Most of the time, the basic {pve}
-network setup is stable and does not change often, so rebooting should not be
-required often.
+One way to apply a new network configuration is to reboot the node.
 
 Reload Network with ifupdown2
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-With the optional `ifupdown2` network managing package you also can reload the
-network configuration live, without requiring a reboot.
+With the 'ifupdown2' package (default since {pve} 7), it is possible to apply
+network configuration changes without a reboot. If you change the network
+configuration via the GUI, you can click the 'Apply Configuration' button. Run
+the following command if you make changes directly to the
+`/etc/network/interfaces` file:
 
-Since {pve} 6.1 you can apply pending network changes over the web-interface,
-using the 'Apply Configuration' button in the 'Network' panel of a node.
-
-To install 'ifupdown2' ensure you have the latest {pve} updates installed, then
-
-WARNING: installing 'ifupdown2' will remove 'ifupdown', but as the removal
-scripts of 'ifupdown' before version '0.8.35+pve1' have a issue where network
-is fully stopped on removal footnote:[Introduced with Debian Buster:
-https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=945877] you *must* ensure
-that you have a up to date 'ifupdown' package version.
-
-For the installation itself you can then simply do:
-
- apt install ifupdown2
+----
+ ifreload -a
+----
 
-With that you're all set. You can also switch back to the 'ifupdown' variant at
-any time, if you run into issues.
+NOTE: If you installed {pve} on top of Debian, make sure 'ifupdown2' is
+installed: 'apt install ifupdown2'
