tar requires two executions, one to create the
archive and one to remove it. This has advantages
and disadvantages. cpio -p can do it in one pass,
but requires that you expand the directories with
find or provide a list file. Again, sometimes a
good thing, sometimes not. cpio can also create a
tree of links if you are on the same file system.
Useful for moving large files with minimal disk
activity (remove the original links afterwards).
