On the source server (A), I got a file /opt/resources/xxx and a hard link /etc/apache2/sites-available/xxx pointing to this file.
On another server (B) I got the same structure /etc/apache2/sites-available/xxx hard linked to /opt/resources/xxx
I rsync on server (A) towards server (B) all changes under /opt
When I change file xxx on server A, and then rsync to server B these changes are reflected. /opt/resources/xxx on server B contains my changes I made on the same file on server A.
The only thing I don't understand is that the file /etc/apache2/sites-available/xxx doesn't contain the change.
It appears as if rsync breaks the hard link, but probably I'm missing some configuration option.
Which one ?
