I used Solaris on a previous job. Ii I remember correctly I had a Sunblade 1500. Really cool machines! And good looking too
I was so happy when I learned about the OpenSolaris project. This project was being promoted by Sun. The OS had some really nice features like Dtrace and the ZFS file system with a "time machine" so you can take snapshop of files and such.
So what happened to this obvious superior OS with a bright future? Oracle happened... After Oracle bought Sun nothing happened with OpenSolaris. It was quiet. And then Oracle decided to pull the plug. OpenSolaris died. I'm still not over this...
I very much enjoy Solaris. Working with Solaris Zones is pretty cool. Oracle has phuqd it up. I can't get them to call me back for support licenses for my x64 machines. Aggravating because you can't download Recommended Clusters without a support contract, anymore. Thankfully I don't expose any native services to the Internet and compile my own stuff, but that doesn't protect me from local elevation exploits.
One thing I really love about Solaris is all the skript kiddies who try to plant and execute binaries by way of poorly programmed PHP sites: those binaries are always Linux. Of course, marking certain file systems as non-executable helps, too.
Screw you, Oracle. Solaris is dead; Long live Solaris!
