Note :

1-) Problem is that livinst (Anconda) produces an 8 GB USB install with 
no firstboot resulting in a VM with no way to login.
root does not work either as a login.

 - it ends up with gdm "other" login?

I informed sdz of this on #sugar-meeting

*-Note with soas.spin the Anaconda screen is located and obscured behind 
the sugar-terminal screen. You have to exit terminal to see it.

***See testing results:

*-This happened with both a USB install and with a booted CD to a 2nd 8 
GB USB
-soas-i386-20100623.16. from a USB-script created USB)
-soas-x86_64-20100625.15.CD using a CD

2-) Re:
attaching the ISO to the
virtual CD drive, boot the VM using the CD drive:


VMworkstation 6.5.3 build-185404:  (Ubuntu 9.04)
liveinst on  soas-i386-20100625.15.iso (latest)
--- it crashed sugar - tried 3 different memory settings 256/1024/1616
--- zyx-liveinstaller (yum install zyx-liveinstaller) also crashes in 
similar manner.

Oracle Virtualbox (f12):
 liveinst on soas-i386-20100625.15.iso (latest)
--Install proceeded normally. (needed to reinitialize disk)
--no firstboot resulting in a VM with no way to login. root does not 
work either as a login.

*-Note with this soas.spin the Anaconda screen is located and obscured 
behind the sugar-terminal screen. You have to exit terminal to see it.

There is definitively something wrong with Anaconda/firstboot/gdm setup 
here.
Not a Usable install at the moment.
