--datadir=/usr/share/kbd: This puts the kbd data files (fonts, keymaps, and such) in the /usr/share/kbd directory, as the FHS suggests. rm -f /usr/share/kbd/keymaps/i386/qwerty/defkeymap.map.gz: We remove this file because we don't know which keymap you need to use. We will be defining the default keymap in chapter 7 when the system configuration files are created.
