I toook the plunge anyway on my testsystem and installed M12-alpha 64bit.
1. There was an INIT problem on booting up and on booting down the live-dvd (respawning ID: 'z6' at a rate where the deamon stopped it ). I had to forcibly (on/off switch) powerdown.
2. After rebooting I installed right away and did not have any problem selecting drive sdb to install into and install grub into the bootdisk MBR. All available drives were selectable.
Selecting to reboot did not work. Apparently the same problem that appeared on booting up the live-DVD happened at powering down after installation.
3. Another issue (probably related to the 'trying to powerdown' issue and not ejecting/releasing the dvd):
it ejects when I shut down the install. lol
That too here, with no disk in it.....
4. Is the message "This is an unsecured session" [at login after booting live-dvd] a 'new' informational message - or is it an error message?
Wording should (in my opinion) be changed, as this will for sure not win over anyone who sets out to try such a live-dvd....
