Progress (maybe)

Rather than try to remove the BootX file temporarily I went back to my 
excludes list and added /System/Library/CoreServices/BootX - not the 
previous more general /System/Library/CoreServices/ trial.

That took care of the latest problem and I believe in limiting the 
exclude to just the BootX file I will not introduce any system 
inconsistencies.  Such is based on my reading everything I could find on 
OS X BootX - specifically its role in the boot process. I can't see 
where it would change within a system update (e.g. 10.4.2) version, and 
probably not even within an upgrade version (e.g. 10.4).  Upgrades and 
updates trigger a full asr clone immediately before and after to 
separate volumes, and the rsync differential updating of a clone would 
not span such a system change. 

If anyone thinks I might not have grasped the dynamics of the BootX file 
please speak up.

I have subsequently noted another issue with rsync that I think needs 
cleared up though.  If on my source volume I have a file on my desktop 
and I trash such, then boot to a third volume to perform the rsync 
differential update of the source clone I get the following error.

rsync: delete_one: unlink 
"/Volumes/LaCie_Disk_B/Users/Chinook/Desktop/._diffclone" failed: No 
such file or directory (2)

In this case "diffclone" was the file I trashed on the source volume and 
it gets deleted on the source clone.  I assume "._diffclone" was the 
associated metadata on the source and was not present on the clone.  So 
why should I get an error from rsync?

If I don't settle these questions before "publishing" the scripts, I'm 
sure to get a load of questions after :-)

Thank you,
