|"Linux was initially designed to run on the Intel 32-bit platform. Though it has been ported to a larger number of hardware bases later, it still lacks the efficiency of NetBSD when it comes to free portability."
Current linux 2.6 is near of the number of platforms supported in netbsd if not more.
"Linux (also FreeBSD, OpenBSD, NetBSD) lags from commercial software like Microsoft Windows 2000, Microsoft Windows Server 2003, Sun Solaris, IBM-AIX and others when it comes to supporting the installed bases."
Wrong. IBM sells you support for Linux, Sun too. Sun has been selling linux servers for a while. So does HP. Those three sel you hardware + support.
"Linux distributions are numerous and so are the numbers of certifications available in the market"
So go and use redhat. Why would you use turbolinux, unless you're stupid? Linux is about choice. There are thousand of distros because there're diferent needs. For servers/workstations I recommend you redhat/novell.
"Big commercial systems dealing with terabytes of information or million dollar investments ought to put support, maintenance and stability of their currently-running systems first to anything else. What happens if something breaks?"
"Big commercial systems dealing with terabytes of information"? You mean systems like the 512-cpu 2TB RAM altix SGI sells with linux, and no option to choose other OS? If you want support you call IBM, SUN or HP and you use the support contract you probably have already contracted with them, because if you want support.....you contract it, no? i mean, were you expecting to being able to "download a support"? No, linux still don't gives you that.. :-)
"Another region of space where almost all free system-level software including Linux, FreeBSD, OpenBSD and others freak out is upgradeability"
I can run linux from a handheld device to a 512-cpu-and-docens-of-disks SGI Altix. That's a platform scalability you won't find in commercial unixes (they don't support handheld devices) neither in Microsoft product (biggest version of win 2k3 for itanium supports just two partitions of 64 CPUs each one, FAR from the 512 CPUs of a SGI altix running linux). And it does that in docens of hardware platforms, unlike windows (it just supports x86, opteron and itanium) or Sun (just x86 or sparc) or AIX.
Exactly where is linux lacking "upgradeability" in hardware? It must be in a windows for s390 (doesn't exists), solaris for itanium (doesn't exist) or aix for sparc (doesn't exist - linux will run ok on those three hardware plaftorms)
"Even once when properly configured, who is there to maintain and support these systems 24/7 around the year?"
Redhat/IBM/Sun/HP/Novell/SGI support and a engineer you've obviously contracted? I guess you've looked and considered all the different offerings there are TODAY (not 5 years ago, which is the enterprise world you seem to be describing) in the market from al vendors, for your enterprise, true " final-year student of Informatics"?
Really, this article is FUD in its whole. Sure, nobody gives you free support for what you download from kernel.org, _what_ made you think that, Subhasish Ghosh? Support is not "downloaded", it's "contracted". You don't get support using debian neither you won't find support using a cracked version of win2003 or solaris. Why on earth do you expect to get free support from OSS community? Are you aware that linux is the fastest growing OS platform on servers? That's probably because the people in charge of buying those servers actually have a _clue_ of how the world works, and buys support from bug vendors.
Unless you want to support yourself with your own engineers, which is what many people does and what you can't do with comercial vendors. Remember, Linux == CHOICE.

|(An for those who think I'm joking about of th numbers of platforms supported in linux are near of netbsd if not equally or more - each directory under arch/ can support several "subarchitectures": http://www.kroah.com/log/2004/09/29#more_archs )|

|diegocg, I have to disagree with this statement of yours...
>And it does that in docens of hardware platforms, unlike windows (it just supports x86, opteron and itanium)...
Actually, Microsoft dropped support for the Itanium. http://slashdot.org/article.pl?sid=05/01/06/2248245&from=rss

|Microsoft ONLY dropped suport of XP for Itanium. W2K3 is supported. HP killed their WORKSTATION Itanium line... not the server line. Note that everyone is allowed to equate HP == Itanium for the moment. If HP gives it up, Itanium will be dead.
