I tried the 4-in-1 iso earlier and here's my experience with it:
The Default Live mode and Core mode both brought up the following error:
Out of memory: kill process 670 (getty) score 1 or sacrifice child
Killed process 670 (getty) total-vm:2304KB, anon-rss:56KB, file-rss:448KB
The process number and KB values are different each time, but the rest of error is always the same.
Core-Basic: Works up to where you select the keyboard mapping and language at the dialogs. After you click OK, it puts the screen in standby mode and doesn't go any further (same problem as with the last rolling). However running core-basic kmap=us lang=en_US
at the command line makes it work fine.
Just-X and Base: Boots all the way in without any issues.
