[ale] interesting problem

[Jim Kinney]

Imagine a giant collection of files, several TB, of unknown directory
names and unknown directory depths at any point. From the top of that
tree, you need to cd into EVERY directory, find the symlinks in each
directory and remake them in a parallel tree on the same system but in
a different starting point. Rsync is not happy with the relative links
so that fails as each link looks to be relative to the location of the
process running rsync.

It is possible given the source of this data tree that recursive,
looping symlinks exist. That must be recreated in the new location.

It looks like a find to list all symlinks in the entire tree then cd to
each final location to recreate is best. That can be sped up with
running multiple processes splitting the link list into sections.

Better ideas?

gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
