Good Evening, I just uploaded FAI 3.4.8 to Ubuntu Precise Pangolin which will become Ubuntu 12.04 LTS in April 2012.
I made some ubuntu specific changes (sources.list, added aptitude to make-fail-nfsroot.conf etc., the usual stuff) Did some standard tests (means: calling make-fai-nfsroot -vvvv and check the resulting nfsroot). Will test it further with local deployments and other integration tests. Regards, \sh
