What ever happened to "Stateless Linux"?

[Phil Regier]

It would appear that the guides which popped up at the time of the 
FC6-FC7 transition have gone more or less defunct since then:

http://fedoraproject.org/wiki/StatelessLinux

It would also seem that the URLs referenced by the above under

http://people.redhat.com/~law/

have not been updated since FC7.  What is the current stated of 
Stateless development under Fedora and related distributions?  Have the 
specialized tools been deprecated with no replacement, or are there new 
tools to fill any possible gaps?

Thanks...

Phil
