			==== Old notes ====

			In the past, for older versions of backuppc, some special files were not properly restored and I had to do this:
	* ''check for errors (possibly failed restoration of some symlink and mknod...) and create them''		* ''check for errors (possibly failed restoration of some symlink and mknod...) and create them''
