[wplug-internet] CentOS 7 RC

[Pat Barron]

At least for our current situation, WPLUG is planning a server migration 
to one of the new, lower cost Linode offerings, that is going to involve 
doing a complete server rebuild anyway - our current server is a 32-bit 
install, and the newer Linode offerings only support 64-bit.  Since we 
need to do a complete rebuild anyway, we might as well do so with CentOS 
7, as long as we're at it.

If we could just bring up the current virtual disk image from our server 
under the new lower cost service offering, I'd totally want to keep it 
on CentOS 6 - I too see no reason to upgrade for the sake of upgrading, 
given Red Hat's lengthy support timeframe - I don't like to change 
things simply for the sake of changing, so I ordinarily would not be 
enthusiastic about upgrading at this time, unless there were some 
specific new feature in RHEL 7 that we really wanted.  (I know that 
Justin is very enthusiastic about the idea of running a distro that uses 
systemd, which is being used in RHEL as of RHEL 7 - though of course, I 
personally see systemd as more of an "anti-feature" than anything 
else....  ;-) ).
