@rene: Weird. How is the boot failing - any error message? You might need to boot with "quiet" and "splash" removed from the kernel command line to see what's going on .. adding "debug" or "debug=y" to the kernel command line will give even more info (one will debug to the screen, the other to a file in the ramdisk, can't remember which is which.)
I booted my 4Gb persistent jaunty install today, so I promise it's not a figment of my imagination this does work! Oooh .. another thought: are you booting on a machine that uses LVM or kernel RAID? If so you might be hitting bug #385305 .. -- casper-rw fs not cleanly unmounted on persistent live USB shutdown https://bugs.launchpad.net/bugs/125702 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
