>что означает строка Epoch ? The Epoch term allows rpm packages to replace old packages with slightly different names, and also where rpm considers the new package version number to be lower than the installed package. Simply increment the Epoch in the new package specification file, and rebuild the new package.
When RPM can't decipher a package's version number, it's time to pull out the Epoch tag. This tag is used to help RPM determine version number ordering. Here's a sample Epoch tag line: Epoch: 42
This line indicates that the package has an epoch number of 42. What does the 42 mean? Only that this version of the package is newer than the same package with an epoch number of 41, but older than the same package with an epoch number of 43. If you think of epoch numbers as being nothing more than very simple version numbers, you'll be on the mark. In other words, Epoch is the most significant component of a package's complete version identifier with regards to RPM's version comparison algorithm.
