Coming in late here.
The --remove-destination is necessary because /etc/localtime is a
symlink. It points to /usr/share/zoneinfo/Factory. If you do cp -fv,
it overwrites Factory with the [xxx] zoneinfo, which is not the
desired effect. The symlink /etc/localtime still points to
/usr/share/zoneinfo/Factory, you've just overwritten Factory. With
--remove-destination, the destination (/etc/localtime) is removed
before attempting to read it. This also solves the problem where /usr
is not mounted (see the note in LFS).

Binary files dest/usr/share/zoneinfo/Factory and
