RE: Slashdiot article about P6

I'm not meaning to speak for David, but he appears to be referring to the Linux 
UPGRADE process, not Linux operational issues. 

We have been running Linux in production for years and have had very few 
operational issues.  We can easily clone a new Linux server from an existing 
one.  But when it comes time to upgrade we have had to start from scratch, 
building a new server and migrating the applications and data, and then do 
extensive testing before going to production.  Our iSeries upgrades normally 
only require upgrading the O/S in test, (usually no application or data work at 
all) normal operation for two or three months, then upgrading the production 
O/S.  Linux upgrades require days, and a team of administrators and 
programmers; iSeries upgrades usually require half a day and my time only.  I 
have never had to rebuild a production iSeries after an upgrade.

In the event of a complete hardware replacement i5's only require a relatively 
simple unload/reload, no application or database reinstallation, etc.  
Compatibility issues are almost unheard of.

Certainly Linux is exceptionally reliable; but it is nowhere near the i5OS in 
ease of use and built-in, out of the box capabilities.

Uh, right ... I've had problems with just about EVERY linux upgrade

I've

ever done ... none of them were completely seamless.  When I upgraded

to

Fedora Core 4 my database was hosed for a while.

i don't know your specs, requiremnts and the software you used/
installed but i am running a linux based os for server and client and i
got not a single problem at all with the os for years. one server is
running for over a year without a single reboot. and don't mix os
problems with application problems.

my 2 cents
