I've just committed a patch to CVS that adds a --safe-links option. It
causes absolute links to be ignored and relative links to be ignored
if they point outside the destination tree.

I'd appreciate it if a few other people could test it out. I think
I've covered all the cases but it is certainly something that is easy
to get wrong.

with -v rsync will print:

     ignoring unsafe symlink foo -> /etc/passwd

if it finds an unsafe symlink.

On another note, I'm probably going to be doing a new rsync release
this weekend. If I track down the "rsync hanging" bug before the
release then I'll call it 2.1.0 otherwise I'll call it 2.0.19. Phil
Hands is helping me track down the hanging bug (thanks Phil!). Phil
also bought be some pizza for dinner tonight (despite living at the
other end of the earth!) so I'm doubly grateful, and slightly overfed :)
