The code name for Sleeper OS's development distribution is “Vicky” (“Version In Continuous Kernel Yielding”), aliased to “unstable”. Most of the development work that is done in Sleeper OS is uploaded to this distribution. This distribution will never get released; instead, packages from it will propagate into testing and then into a real release.

Please note that security updates for the “unstable” distribution are not managed by the security team. Hence, “unstable” does not get security updates in a timely manner.

“Vicky” is subject to massive changes and in-place library updates. This can result in a very “unstable” system which contains packages that cannot be installed due to missing libraries, dependencies that cannot be fulfilled, etc. Use it at your own risk!

“Vicky” is where Sleeper OS's team does their tests, and is marked clean for release by the SourceForge's FTP.

Really? Think twice! No!

As with all Sleeper OS's release names so far (since V3), the “Vicky” distribution takes its name from a *The Fairly OddParents* character. Vicky is the babysitter teenager who makes Timmy Turner's life impossible and does nasty things, among others. It is sometimes a misnomer for “Version In Continuous Kernel Yielding.” While other release codenames progress over time from testing to stable, “Vicky” is forever doomed to be unstable.
