Jonathan Ellis commented on CASSANDRA-3706:
-------------------------------------------
you can compare the raw text just as easily as the digest... it's a bit more
cpu, but still negilible, and same amount of code.
don't think it's worth the trouble to create an option to disable, if you don't
need it just ignore it.
> Back up configuration files on startup

> Snapshot can backup user data, but it's also nice to be able to have
> known-good configurations saved as well in case of accidental snafus or even
> catastrophic loss of a cluster. If we check for changes to cassandra.yaml,
> cassandra-env.sh, and maybe log4j-server.properties on startup, we can back
> them up to a columnfamily that can then be handled by normal snapshot/backup
> procedures.
