New securityonion-rule-update package resolves two issues

We recently released new barnyard2 and rule-update packages:
http://blog.securityonion.net/2014/06/new-barnyard2-nsm-rule-update-and.html 

Some folks have reported a few issues since updating to these new packages, so we're releasing a new version of rule-update which should help with these issues.

The first issue is that rule-update takes longer now.  Per the barnyard2 developers, all entries in the sig_reference table must be deleted when upgrading to this new version of barnyard2.  rule-update then uses barnyard2 to re-populate this table.  Depending on the size of your Snorby database, this may take a while.  The new version of rule-update (released today) will only do a full delete of the sig_reference table once, so subsequent runs of rule-update should be much faster.

The second issue is that users running the Snort engine with the VRT ruleset are experiencing barnyard2 failing with errors like "Returned signature_id is not equal to updated signature_id".  This is due to some wrong entries in the database left by the previous version of barnyard2.  One of the barnyard2 developers wrote a MySQL script to fix these entries and I've packaged it into a shell script called so-snorby-fix-sigs and included it in today's rule-update package.  If you're running the Snort engine with the VRT ruleset, please run so-snorby-fix-sigs and follow the directions (including shutting down all barnyard2 instances).

The updated package version is as follows:
securityonion-rule-update - 20120726-0ubuntu0securityonion20

This new package has been tested by the following (thanks!):
