If there are verification errors, extending will also fail. +Note that a signature can only be extended when the required hash has been +published.

As such, +it can be assumed that extending is only possible after this happend (which +means it may take slightly above a month). + +To prevent data corruption, a copy of the signature file is created during +extension.

When extending finished successfully, the original +signature file (logfile.gtsig in our example) is renamed with the .old +postfix (logfile.gtsig.old) and the temporary file written under the +original name.
