NAME
       netplan-generate - generate backend configuration from netplan YAML files

SYNOPSIS
       netplan [--debug] generate -h | --help

       netplan [--debug] generate [--root-dir ROOT_DIR] [--mapping MAPPING]

DESCRIPTION
       netplan generate converts netplan YAML into configuration files understood by the backends
       (systemd-networkd(8) or NetworkManager(8)).  It does not apply  the  generated  configura-
       tion.

       You  will  not  normally  need to run this directly as it is run by netplan apply, netplan
       try, or at boot.

       Only if executed during the systemd initializing phase (i.e.  "Early  bootup,  before  ba-
       sic.target  is  reached"), will it attempt to start/apply the newly created service units.
       Requires feature: generate-just-in-time

       For details of the configuration file format, see netplan(5).

OPTIONS
       -h, --help
              Print basic help.

       --debug
              Print debugging output during the process.

       --root-dir ROOT_DIR
              Instead of looking in /{lib,etc,run}/netplan, look in  /ROOT_DIR/{lib,etc,run}/net-
              plan

       --mapping MAPPING
              Instead  of  generating  output files, parse the configuration files and print some
              internal information about the device specified in MAPPING.

HANDLING MULTIPLE FILES
       There are 3 locations that netplan generate considers:

       o /lib/netplan/*.yaml

       o /etc/netplan/*.yaml

       o /run/netplan/*.yaml

       If there are multiple files with exactly the same name, then only one  will  be  read.   A
       file  in  /run/netplan  will  shadow  -  completely replace - a file with the same name in
       /etc/netplan.  A file in /etc/netplan will itself shadow a file in /lib/netplan.

       Or in other words, /run/netplan is top priority, then /etc/netplan, with /lib/netplan hav-
       ing the lowest priority.

       If there are files with different names, then they are considered in lexicographical order
       - regardless of the directory they are in.  Later files add to or override earlier  files.
       For example, /run/netplan/10-foo.yaml would be updated by /lib/netplan/20-abc.yaml.

       If you have two files with the same key/setting, the following rules apply:

       o If  the  values are YAML boolean or scalar values (numbers and strings) the old value is
         overwritten by the new value.

       o If the values are sequences, the sequences are concatenated - the new values are append-
         ed to the old list.

       o If  the  values  are mappings, netplan will examine the elements of the mappings in turn
         using these rules.
