The format is bash. It contains several commonly-edited settings such as timezone; keymap; kernel modules; daemons to load at start-up; etc. It is split up in a few sections to categorize configuration settings: localization, hardware, networking and daemons. -Localization[[L]] +LOCALIZATION[[L]] ----------------- -*TIMEZONE*:: - Specifies the timezone. The setting takes effect on boot by ensuring that /etc/localtime is a symlink - to the correct zoneinfo file. Possible timezones are the relative path to a zoneinfo file starting - from the directory /usr/share/zoneinfo.
