Description Gary Thomas 2011-09-30 04:22:16 UTC 
Now that booting from CDROM mostly works (see http://bugzilla.pokylinux.org/show_bug.cgi?id=686), I tried to boot 'core-image-sato' from CDROM

Build core-image-sato for qemux86, master 9d1db6cc928199f8ac4960e8d4648563ef141427

Firstly, I have found no way to run this image using the 'runqemu' script

Boot the CDROM manually like this:
  $ tmp/sysroots/i686-linux/usr/bin/qemu -serial stdio -m 512 --cdrom tmp/deploy/images/core-image-sato-qemux86-20110930010455.iso

You'll see that it hangs with the splash screen, although you can log into the serial console.  Poking around on the console, it's obvious that this image is not happy running with a read-only root such as the CDROM.

Boot log

This log shows logging into the sato session and trying to restart the X server.
This showed that at least /tmp needs to be writable for this to work, so I mounted
/tmp on a ramdisk and tried again.  The X server tried harder, but still fails.

Saul already pointed this out (slipped through my search though...)
