Re: Copying one hard drive to another - links

[Alvin Oga <aoga@Mail.Linux-Consulting.com>]

hi ya dan

congrats  you found more differences in ln ... :-)
	- very interesting differences in ln
		( see the next test below ... done same way as yours...

	-  .pine having been local to the dir makes
	a difference when my .prinrc023592 file was elsewhere

- yes the hardlinks for gunzip and gzip is not a issue in that
  case since its in the same directory/partitions
	- hardlinks is a problem when it crosses directories
	and partitions since it keeps the leading /

and i did my silly ln tests on a old rh box... 

	Maggie:~> ln --version
	ln (GNU fileutils) 3.16

thanx
alvin

-- re-testing for fun
	-
	- same as your results !!!
