Installation

With the calls of id utility we write the user ID and group ID of current user into user database of newly created system. That way we can operate later inside chrooted environment from the same user as outside.

chgrp utility is not called during the build, as it requires root privileges. Instead it is called later in the postinstall script.

lfs_install

Method lfs_install is empty, which means the package is not installed into chroot at the main stage of the build. Instead it is installed only at pass1 stage, which uses another method for installation. 

lfs_install()
{
    return
}
