2cents about this:

1. If you are setting up Sentinel with puppet you can do audit of a file instead of modifying it on every run http://puppetlabs.com/blog/all-about-auditing-with-puppet this way you can install, configure and start sentinel and puppet will notice that the content changed. You can decide if you want to change the file or if you would like puppet to notice about it.

2. About sentinel, don't know how you are triggering the failover but we discovered a bug on versions prior to 2.8.12 on manual failovers, https://groups.google.com/forum/#!searchin/redis-db/rhommel/... so it was fixed in 2.8.12 and never seen redis taking more than a second.
