I have released updates of the following legacy Ubuntu and Debian S3-based AMIs published in the “alestic” buckets: Ubuntu: 8.04 Hardy, 8.10 Intrepid, 9.04 Jaunty. Debian: 4.0 Etch, 5.0 Lenny More here
I do not recommend that new users start with these AMIs. These AMIs run with older versions of Amazon’s Fedora 8 kernel which have some incompatibilities with Ubuntu and Debian (e.g., XFS is broken). My strong recommendation is for all users to convert to one of the Ubuntu 9.10 Karmic or Ubuntu 8.04 Hardy AMIs which run with a modern, compatible Ubuntu kernel.
