This package is not part of original LFS (on both pass1 and main stages). Package is used for user switching inside chrooted container. After default \Cmd{chroot}{1} we are acting as \Arg{root} user. \Prog{sudo} helps us to return back to general user (automatically). %%% lfs_postinstall %@% IF pass1 Function \Prog{lfs\_postinstall} is not called during pass1, it derives from main build. %@% ELSE The installation settings for package are not performed, as they require root privileges, which we do not have. %@% END-IF
