Skip system table when repair

From ml:

When I run nodetool repair on a node on my 3-node cluster, I see 3 messages like the following:

INFO [manual-repair-6d9a617f-c496-4744-9002-a56909b83d5b] 2011-07-30 18:50:28,464 AntiEntropyService.java (line 636) No neighbors to repair with for system on (0,56713727820156410577229101238628035242]: manual-repair-6d9a617f-c496-4744-9002-a56909b83d5b completed.

Granted, there's no data on these machines yet. Is this normal?

And the answer:
You can discard those. This is saying it cannot repair the system keyspace
(table used internally). It turns those aren't replicated and thus don't need
to be repaired. We should probably update the code to skip trying to
repair the system table but in the meantime this is harmless.
