Installing from the DVD iso. Not the Live Image, Not a netowrk install.
The installer requires a working internet connection
And it tells me about this requirement AFTER it has finished writing partition changes to the disk. This potentially leaves the user with a dead computer if for any reason they cannot configure their network.
Tip: Let the user test the network configuration BEFORE you trash their hard drive. Or atleast mention this requirement. There is no sensible reason for the user to expect this requirement in advance. A person using the the full DVD install like this, might well be doing so because they have no network, or a problematic device.
There are other problems I had with this distro after installing, But to be honest I had lost any sympathy after the installer pulled that on me. I think it is a betrayal of trust. The user is taking a risk and there is no forewarning of it, some will not be lucky.
