Correct me if I am wrong here, and apologies for the delay as this thread
and discussion has really taken off.
My arguments for gentoo is more along the lines of optimization of the
source code for ones hardware.
You mention CentOS and Red hat how optimized is the heart of the system
for the hard ware its running on? How secure are they as an os? Reason I
bring up these questions is that I feel that resource are wasted that
could be used for more important things.
Another thing that I like about gentoo is the hardened profiles as well as
the extra security features that one can setup at the kernel level as
well, but that is going off my point.
I for instance currently even though nothing is running on it have a vps
with 2gb of ram and with no websites or db on there yet just the servers
ram wise i use about 62mb. I look at the low memory foot print as an
advantage in the sense that the rest of the ram can be used for more
