Personally I am not that happy with Kylin. I was simply evaluating it as to ensure an understanding of the broad base of operating systems on the planet. The Simplified Chinese OS did have its entertainment value.
Kylin 2.1 seems to be build of FreeBSD 5.3. I also recently tried FreeBSD 8.2RC. All OSes were run on Snow Leopard through Oracle VirtualBox. The package manager is weak, it builds straight from C/C++ on FreeBSD 8.2RC. On Kylin I haven't even figured out how to build packages yet. I am certain its using a similar method. Ubuntu, CentOS and RHEL is what I am used to deploying production rails apps on. Installation of packages are a breeze, support is good. I think its good to evaluate Kylin in terms of if you want to build an 'off the wall' secure web product whom people do not have experience 'hacking'. It has its value. Also since all packages are built from source, you technically know what is going into the OS as well. The main positive I noticed in FreeBSD/Kylin is that there is an extremely low process count (barely 20 processes on install). One negative I noticed is that during idle time of a command line based OS, that up to 5% of the CPU can be used for interrupt driven processes. I cannot determine what all that CPU power is doing. Ubuntu has a clear 100% idle CPU. One final point, surfing Chinese web sites related to Kylin, there was a request from the Chinese government to support national software products. That also had an interesting ting to the entire affair. Anyway, we all use Nginx, which is built in Russia. It has its entertainment value to see whom else is interested in Kylin as a production web OS. I am actively looking for Kylin 3.0 as well as another individual I met online. --- One final point. The contributors of Kylin are going to have a horrible time re-integrating changes that are in the main FreeBSD trunk back into the Kylin branch (from FreeBSD 5.3). Secure generally means slow to adopt changes, slow to add features etc. Even when completing a port scan on the fresh Kylin 2.1 I noticed port 6000 open and an SSHD server already setup. These things are not secure. Ubuntu installs by default with an SSHD server. However I did notice that inetd was not installed by default and it # of processes was a bit more bare then Ubuntu. Overall it was a fun experiment ! If you are building a site with over 10 million users a day, let me know. I'd be excited to do it with Ubuntu, RHEL, CentOS, Kylin, FreeBSD, Windows Server 2008, or whatever it is. Users are extremely stimulating. :) On Jan 18, 4:31 pm, David Kahn <[email protected]> wrote: > On Tue, Jan 18, 2011 at 2:32 PM, Khalid Shaikh > <[email protected]>wrote: > > > Anyone have experience with Ruby on Rails and Kylin 2.1. > > No..but curious, are you using Kylin for security reasons or other?
