Currently the DHCP Unique Identifier (DUID)\&. +.SH "CONFIGURATION DIRECTORIES AND PRECEDENCE" +.PP +The default configuration is set during compilation, so configuration is only needed when it is necessary to deviate from those defaults\&. The main configuration file is either in +/usr/lib/systemd/ +or +/etc/systemd/ +and contains commented out entries showing the defaults as a guide to the administrator\&. Local overrides can be created by creating drop\-ins, as described below\&. The main configuration file can also be edited for this purpose (or a copy in +/etc/ +if it\*(Aqs shipped in +/usr/) however using drop\-ins for local configuration is recommended over modifications to the main configuration file\&. +.PP +In addition to the "main" configuration file, drop\-in configuration snippets are read from +/usr/lib/systemd/*\&.conf\&.d/, +/usr/local/lib/systemd/*\&.conf\&.d/, and +/etc/systemd/*\&.conf\&.d/\&. Those drop\-ins have higher precedence and override the main configuration file\&. Files in the +*\&.conf\&.d/ +configuration subdirectories are sorted by their filename in lexicographic order, regardless of in which of the subdirectories they reside\&. When multiple files specify the same option, for options which accept just a single value, the entry in the file sorted last takes precedence, and for options which accept a list of values, entries are collected as they occur in the sorted files\&. +.PP +When packages need to customize the configuration, they can install drop\-ins under +/usr/\&. Files in +/etc/ +are reserved for the local administrator, who may use this logic to override the configuration files installed by vendor packages\&. Drop\-ins have to be used to override package drop\-ins, since the main configuration file has lower precedence\&. It is recommended to prefix all filenames in those subdirectories with a two\-digit number and a dash, to simplify the ordering of the files\&. This also defined a concept of drop\-in priority to allow distributions to ship drop\-ins within a specific range lower than the range used by users\&. This should lower the risk of package drop\-ins overriding accidentally drop\-ins defined by users\&. +.PP +To disable a configuration file supplied by the vendor, the recommended way is to place a symlink to +/dev/null +in the configuration directory in +/etc/, with the same filename as the vendor configuration file\&. +.SH "[NETWORK] SECTION OPTIONS" +.PP +The following options are available in the [Network] section: +.PP +\fISpeedMeter=\fR +.RS 4 +Takes a boolean\&.
