5&amp;&amp; rm $LFS/usr/bin/gunzip $LFS/usr/bin/gzip:</userinput> The reason
6we don't simply use <quote>mv</quote> to move the files to the new location
7is because gunzip is a hardlink to gzip. On older distributions you can't
8move a hardlink to another partition (and it's very possible that $LFS and
9$LFS/usr are separate partitions). With more recent distributions this
10isn't a problem. If you run mv to move hardlinks across partitions it'll
11just do a regular <quote>cp</quote> and discard the hardlink. But, we
12can't assume that every host distribution has a new enough kernel and
13fileutils that works this way.</para>
