I guess these are two separate updates, one for Remote Desktop and the  
other for Keychain, right? If that it indeed the case, both had been  
applied already. From Software Update.log:

2007-10-26 23:42:19 +0200: Installed "Remote Desktop Client" (3.2.1)
2007-10-26 23:42:29 +0200: Installed "Backup" (3.1.2)

l’ouverture de session" (1.0)

Just did that. If I understood correctly, there is a pull-down menu  
allowing to select a user account, and then the button you mention to  
reset all ACLs for this user.

In my case there were three users in the menu (me and my GF -- the two  
account owners on my MacBook -- and System Administrator aka root --  
though I did not activate the root account in NetInfo Manager in Tiger  
at any stage). I rebuilt the ACLs for all 3 in sequence.

When I do that now, not only I do get the message you mention (it was  
there already before), but also I do get messages about found and  
unexpected ACLS in /private/var/root/Library/Preferences and /private/ 
var/root/Library. Sounds scary! I hope I did not mess anything up by  
asking to restore default ACLs for root.

 From DiskUtility.log:

Thanks for your help,
