I've been very happy running host-configured minimal Debian 6/7 templates, but now that on iwstack I have the option of using my custom iso, I started wondering if there is any point using the latest Debian netinst (7.5 as of today), instead of using the 7.1 provided.
My question is that is there any difference between a 7.5 installed vs a 7.1 upgraded system? I'd guess that all packages will be updated to the same version, but what happens with the kernel (in KVM)? Does the kernel also get automatically upgraded to the latest dot release versions? Do I need to use dist-upgrade or it's the same with upgrade?
