Decided to check it out today, and hit a snag right out of the gate. I can't seem to get it to permanently use a static IP configuration (instead of DHCP). Apparently they've completely revamped how network settings are handled, and unless I'm missing something, what they've done is just plain retarded. The system doesn't use /etc/network/interfaces the way it used to, and the new GUI-based network settings app is wonky.
Did a bunch of Googling, and eventually tried the procedure outlined here (scroll down about 3/4 of the way to the "More about the Network Manager" section), and it sort of works... but only until the next reboot. Blecchh.
I guess I'll have to figure out how to disable whatever new voodoo it is they've implemented, so that I can just configure things manually in /etc/network/interfaces (the old fashioned way).
I really want to like this new release, since it supposedly rolls out some nifty new features. But if the network configuration snafu is any indication, I'll be sticking with the 8.04 LTS release for a while yet.
