-By 1996/12/04, the utmp element size has been changed, in order to
-allow for longer usernames. This change renders all existing wtmp
-files unusable. The cvt-wtmp utility is provided as an aid to convert
-your old wtmp files into the new format, so you don't lose the
-existing track record.
-
-The tool cannot handle gzip'ed wtmp backups, so unzip them first if
-you need. Then simply call it as:
-
- ./cvt-wtmp /var/log/wtmp*
-
-The old wtmp files are being renamed to <file>.bak, so nothing will be
-lost even in case of a failure. If you are only about to test whether
-the tool will grok your files correctly, you can run it as:
-
- ./cvt-wtmp -n /var/log/wtmp*
-
-The tool tries an ``educated guess'', based on the reasonability of
-the timestamp values in the wtmp file. If it fails to recognize the
-format of your wtmp, it normally bails out, or at least ignores
-garbage records. In this case, rename the .bak files to the original
-name, and try to force the conversion:
-
- ./cvt-wtmp -f /var/log/wtmp.xxx
-
-Make sure to verify the result however!
