OpenSolaris vs. Linux, For Linux Users
An anonymous reader writes "With Sun busy being swallowed up by Oracle, should Linux geeks pay any interest to OpenSolaris? TuxRadar put together a guide to OpenSolaris's most interesting features from a Linux user's perspective, covering how to get started with ZFS and virtualisation alongside more consumer-friendly topics such as hardware and Flash support."
Using JFS:
$ time cp data test2
real 0m0.062s
user 0m0.000s
sys 0m0.040s
Anyone who likes Linux and wants to try OpenSolaris should give Nexenta a look. It's basically Ubuntu using the OpenSolaris kernel instead of Linux (so GNU/Solaris?). All the fun of Solaris, all the ease of apt. I can't find builds for anything except x86 though.
OSOL's own site lists several different distributions. There's also auroraux, which aims to have its own kernel source repository and freedom from any remaining binary bits: http://www.auroraux.org/index.php/Main_Page
I was recently tasked with doing an inventory and repurposing of a stack of older Sun machines (Sunfire, Netra, etc).
What I discovered is that OpenSolaris won't even install on some of the models. Install from CD? Nope. Install remotely via a network install? Nope, and let me go on record as saying that the network install process is *absurdly* complex.
On the other hand, I popped a Debian CD in, and it installed beautifully once I booted into expert mode and loaded fdisk (parted blows when dealing with Sun tables).
That's right, Linux was easier to work with on these Sun servers than OpenSolaris. OSOL has some really cool features (ZFS and DTrace, for example), and I've mucked around in it on my x86 boxes before, but overall Linux is still easier to work with in my experience, even on Sun servers.
I always keep an OSOL VM in VirtualBox, but it doesn't see much use. I'd rather use Linux or BSD.
I'll take a look at OpenSolaris when there's at minimum 3 variants of it being developed.
Here is a list of 13 OpenSolaris distros as of March 2009:
