It's a script that uses the rsync command listed below.  It's the rsync 
command
below that that issued the error messages.

    My mom and dad put things on 1 partition, so do many non-computer
types.  It's not flexible or safe enough for my needs.  How would you 
separate out
programs and data?  How do you upgrade your OS without destroying your 
data?
How do you implement different backup policies for different types of 
data? 

If you want to move your home partition to a different part of the disk 
or with
different make params or even a different file system, how do you do that?

When you move your home partition, to a new disk, how do you switch out the
home, or media, or whatever partition without rebooting?  This isn't 
MS-DOS or
Windows... If you have everything formatted into one partition, how do 
you make
snapshots.  If you only have 1 partition, where you do daily backups 
to?  You DO
run daily backups, don't you?

The results I posted below -- the util.. um... gee, let me think... I'm 
posting to
an rsync list.... maybe it was visicalc?... nah... rsync! what would I 
be posting to
this list for if this wasn't about rsync?

Panic would be to my state like like famine to my missing my afternoon

I thought I did provide the tech details... file system, rsync command 
that produced it,
kernel version. file system params...what more did you have in mind?


Missing abbreviated xattr value, "trusted.SGI_ACL_DEFAULT", for 
"/home.diff/Bliss/Documents/law/Pictures/Scans/SwordArtOnline" 
The name "trusted.SGI_ACL_DEFAULT" is the name of an extended attribute..
For some reason, the name is present in the index of extattrs, but the
content associated with that ACL is missing.

Another reason for splitting up file systems:... did you notice the execution
time at the end: rsync took 135m, 26s.   Do you know how long it would take
if I added about 20x to that space?  What's this about 1995?  Do you still
have the same data needs now that you did in 95?  

But all that's apart from the output of "the util" (that this list is about) with
it's version number listed below even!  Cripes.
