Ah I found another workaround / hack someone left on a comment in my original askubuntu question.
It's definitely a hack but it got me around this bug. I extracted the initrd.gz file served by my TFTP site using this guide: http://www.thegeekstuff.com/2009/07/how-to-view-modify-and-recreate- initrd-img/ Then, I edited the included bin/fetch-url file to add the following lines before the proto= line near the bottom: # Remove /cdrom prefix: prefix="/cdrom" url=${url#$prefix} Then I repackaged the initrd.gz file, copied it back to my tftp server and everything worked. Definitely a nasty hack, but it got the image working for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575652 Title: PXE install prefixes /cdrom to squashfs location, fails to find it To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/live-installer/+bug/1575652/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
