      I really miss the old simple pxelinux menu and the ability to easily boot livecds using memdisk iso raw. It was a really simple way to have a an easily managed menu of bootable utility cds that boot directly into the live environment through tftp. If I wanted to upgrade a live version, all I had to do was replace the iso file. It just worked to boot livecds on every machine I have.

      Upgraded to 1.2 with ipxe and maintaining a boot menu with the advanced menu became a lot more complicated. Trying to use memdisk iso raw with clonezilla livecd doesn’t work anymore because it can’t find the filesystem.squashfs. I had to extract the files from the livecd and use the following advanced boot menu code:

      :CLONEZILLA
      kernel [url]http://${fog-ip}/fog/iso/clonezilla/vmlinuz[/url]
      initrd [url]http://${fog-ip}/fog/iso/clonezilla/initrd.img[/url]
      imgargs vmlinuz boot=live config noswap nolocales edd=on nomodeset ocs_live_run=“ocs-live-general” ocs_live_extra_param=“” ocs_live_keymap=“” ocs_live_batch=“no” ocs_daemonon=“ssh” usercrypted=Kb/VNchPYhuf6 ocs_lang=“” vga=788 nosplash noprompt fetch=[url]http://${fog-ip}/fog/iso/clonezilla/filesystem.squashfs[/url]
      boot ||

      The above boots a working clonezilla, though not identical to the livecd. This does not seem an improvement over the simple livecd booting method under the old pxelinux menu:

      LABEL clonezilla
      MENU LABEL Clonezilla Live
      LINUX clonezilla/memdisk
      APPEND iso initrd=/clonezilla/clonezilla.iso raw

      I’m finding the new ipxe boot menu means extracting files and updating a custom set of imgargs for every livecd. I’m no linux expert and I’m finding the correct imgargs to work with ipxe a challenge and testing a largely trial and error exercise for each livecd.

      I wonder if there is a way to boot pxelinux from ipxe so that the old menu system could be used?

        Have you, possibly, tried using:

        initrd [url]http://${fog-ip}/fog/iso/clonezilla/clonezilla.iso[/url] iso raw

        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

        Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

          According to this: [url]http://forum.ipxe.org/showthread.php?tid=6879[/url]

          initrd [url]http://192.168.xxx.xxx:port/mxp14.iso[/url]
          chain memdisk iso

          Notice the lack of “raw” at the end? Maybe this will help?

          initrd http://${fog-ip}/fog/service/ipxe/iso/ubuntu-14.04-64.iso
          chain memdisk iso ||
          echo failed to boot
          prompt
          goto MENU[/code]

            Just because it was harder, doesn’t not mean that it’s worse.

            While I understand the frustration, the whole reasoning to move to ipxe was to gain access to http downloading vs. tftp. Http gains access to full spectrum bandwidth capabilities of your network. Tftp was always extremely slow, like limited to 10Mbps.

            There’s so many resources out there, yet everybody seems to think that the FOG Team must be doing something to make your lives harder.

            I Assure you all, that this is not the case, nor has it ever been. If anything, the reason for all the changes was due to requests from all of you before.

                          Sorry for the delay in making it back here. I only have time to experiment with this infrequently.

                            This works! It appears that memdisk ISO is not necessary and causes the squashfs errors. I have tested this on clonezilla livecd and parted magic livecd so far and will report back if run into problems with other livecds.

                            Thanks for your help and I hope others find this information.
