Re: [rdiff-backup-users] Write-once read-many problem

[Sheldon Hearn]

Why do you think the failure to modify the restore log makes a 
difference?

As you requested, I made it writable, and still get "Operation not 
permitted" on an unrelated object (currently the packages 
subdirectory).

Fresh trace included.

Anyone actually know what rdiff-backup thinks its doing here?  If I 
could find the wayward chmod/chown in the source, I'd just hack it out, 
since it's bogus for my application, and probably bogus in any restore.

Ciao,
Sheldon.
