+`cicustom`: `[meta=<volume>] [,network=<volume>] [,user=<volume>]` ::
+
+Specify custom files to replace the automatically generated ones at start.
+
+`meta`=`<volume>` ;;
+
+Specify a custom file containing all meta data passed to the VM via cloud-init. This is provider specific meaning configdrive2 and nocloud differ.
+
+`network`=`<volume>` ;;
+
+Specify a custom file containing all network data passed to the VM via cloud-init.
+
+`user`=`<volume>` ;;
+
+Specify a custom file containing all user data passed to the VM via cloud-init.
+
`cipassword`: `<string>` ::
Password to assign the user. Using this is generally not recommended. Use ssh keys instead. Also note that older cloud-init versions do not support hashed passwords.
IP addresses use CIDR notation, gateways are optional but need an IP of the same type specified.
+
The special string 'dhcp' can be used for IP addresses to use DHCP, in which case no explicit gateway should be provided.
-SLAAC is not supported by cloud-init but at least netplan activates SLAAC when selecting 'dhcp' so it should work with up-to-date netplan versions.
+For IPv6 the special string 'auto' can be used to use stateless autoconfiguration.
+
If cloud-init is enabled and neither an IPv4 nor an IPv6 address is specified, it defaults to using dhcp on IPv4.
