[William Ballard] > I like my transactions to have ACID consistency and dpkg does not > have this by design - apt does. "You keep using that word. I do no think it means what you think it means." Let's see how ACID-compliant apt install runs are.... Atomicity - no. Your install does not, for example, get rolled back if a random postinst script fails. Not even that package gets rolled back. Consistency - this seems to be what you were talking about. Isolation - nope. If you upgrade, say, svn and libsvn0 together, there's a window where users can find themselves using the new svn with the old libsvn0, or vice versa. Durability - I have no idea if dpkg or apt run 'sync' or 'fsync' at useful points (like at the end of the install). Kind of a moot point, though, when you don't have atomicity. So, you're about 1/4 right. Or, being charitable, if you really meant "*only* the Consistency part of ACID" when you said "ACID consistency", then you were right but quite misleading. Peter
