Linux does what you need -- it offers you guest-level utilities that interface with the proprietary storage system back-end (EBS) that is offered by your choice of hosting vendor (Amazon). So what's the problem with using Linux? Why sound so apathetic-yet-confrontational (re: "Linux offers this, FreeBSD doesn't")? There is absolutely no shame in any way/shape/form in using an OS that meets your needs/requirements. I can't speak for others, but if that's Windows, great -- if that's Linux, great -- if that's some proprietary thing that only 30 people use, great. I really couldn't care less what someone uses, as long as it allows them to accomplish what they need. Otherwise, if this is some sort of "deal-breaker" for you and you absolutely need this functionality on FreeBSD, my advice is to talk to Amazon. EBS is a closed, black-box-proprietary thing. The userland utilities they may offer on Linux, depending on how they work, could be made to work on FreeBSD (and NOT through Linux emulation, thank you very much). If this is something you want, you should talk to them about it. They aren't going to know/care unless you tell them it's something that interests you as a customer. If they respond "that's nice, we have only a small interest in FreeBSD", then you should be able to take that response and make decisions based upon it, depending on what your needs are. ***You*** are responsible for those choices, not anyone here. :-) So please do not try to make this a "Linux vs. FreeBSD" thing when the actual limitation here is being indirectly imposed on you by your choice of hosting vendor. -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Making life hard for others since 1977.
