86In the remainder of the text, we use the default <path>/dev/sd*</path> block
87device files as partition. You can also opt to use the symbolic links in the
88<path>/dev/disk/byid</path> or <path>/dev/disk/by-uuid</path>. These names are
89not likely to change, whereas the default block device files naming depends on
90a number of factors (such as how and in what order the disks are attached to
91your system). However, if you do not intend to fiddle with the disk ordering,
92you can continue with the default block device files safely.

530You will probably only use one or maybe two locales on your system. You have to
531specify locales you will need in <path>/etc/locale.gen</path>.

551You can select your desired locales in the list given by running <c>locale -a</c>.

555We strongly suggest that you should use at least one UTF-8 locale because some
556applications may require it.
557</warn>
558
559<p>
560The next step is to run <c>locale-gen</c>. It will generates all the locales you
561have specified in the <path>/etc/locale.gen</path> file.

573Once done, you now have the possibility to set the system-wide locale settings.
