rsync - May 2006 - Rsync linked disk

Hi,

 

I have a problem rsync disk that is linked in the following way:

 

/a/b/c/d/e -> ../e

 

We use that in order to create linked tree which has link to kind of
tools we need to rsync and thus not worry on disk capacity cause we can
add linked disks as many as we can.

 

We use rsync module with chroot for security reasons as follows: 

[d]

Path = /a/b/c/d

Chroot = true

 

The problem is that I cannot rsync <rsync_server>::[d]/e

 

Any work around for that????

 

 

 

Thanks,

Oren Mark

The chroot system call will prevent any access from outside the root, so
it's impossible to access /a/b/c/e from inside the chroot area if you
use a symlink.  If you can setup a "bind" mount in your /etc/fstab
file,
you can use that instead (this is supported by modern GNU tools):

/a/b/c/e	/a/b/c/d/e		none	bind

Since the content is now mounted in two places, the path restriction of
/a/b/c/d will now allow you to access the content in "e".

The only other alternative I can think of is to switch which spot is the
real directory and which spot is the symlink:

rm /a/b/c/d/e
mv /a/b/c/e /a/b/c/d/e
ln -s ../d/e /a/b/c/e
