NAME

       ltsp ipxe - install iPXE binaries and configuration in TFTP

SYNOPSIS

       ltsp [ltsp-options] ipxe [-b binaries]

DESCRIPTION

       Generate  the  ltsp.ipxe  configuration  file  and  install the required iPXE binaries in /srv/tftp/ltsp:
       memtest.0, memtest.efi, snponly.efi and undionly.kpxe.

       An ltsp-binaries package is available in the LTSP PPA that provides them; otherwise,  some  of  them  are
       automatically found in the ipxe/memtest86+ packages.

OPTIONS

       See the ltsp(8) man page for ltsp-options.

       -b, --binaries[=0|1|""]
              Reinstall the iPXE binaries in TFTP even if they already exist.  Defaults to "", which means "only
              install the missing ones".  Note that the --overwrite flag doesn't affect  the  binaries,  they're
              only controlled by the --binaries flag.

ADVANCED IMAGE SOURCES

       This  section  is for advanced LTSP sysadmins.  Normally, image sources are simple names like "x86_64" or
       full paths like "../path/to/image".  But the "img_src" parameters  are  much  more  flexible  than  that;
       specifically, they are series of mount sources:

              img1,mount-options1,,img2,mount-options2,,...

       ...where  img1  may  be  a simple name or full path relative to the current directory, and img2+ are full
       paths relative to the target directory.

       Let's see an advanced example: suppose that your clients came with Windows, and that you copied a live CD
       into  C:\ltsp\ubuntu.iso,  and  you  want your LTSP clients to use that for speed. First, disable Windows
       fast boot and hibernation, so that Linux is able to mount  its  partition.   Then  create  the  following
       "method" in ltsp.ipxe:

              :local_image
              # The "local_image" method boots C:\ltsp\ubuntu.iso
              set cmdline_method root=/dev/sda1 ltsp.image=ltsp/ubuntu.iso,fstype=iso9660,loop,ro,,casper/filesystem.squashfs,squashfs,loop,ro loop.max_part=9
              goto ltsp

       Explanation:

              • The root=/dev/sda1 parameter tells the initramfs to mount /dev/sda1 into /root.

              • Then  the  LTSP  code will look under /root/ltsp/ and mount ubuntu.iso using the loop,ro options
                over /root again.

              • Then the LTSP code will look under /root/casper/ and mount filesystem.squashfs over /root again.
                This  casper/filesystem.squashfs path is where the live filesystem exists inside the Ubuntu live
                CDs.

       So while this long line gives a good example on using advanced image sources, the LTSP code  is  actually
       smart enough to autodetect Ubuntu live CDs and filesystem types, so one could simplify it to:

              :local_image
              # The "local_image" method boots C:\ltsp\${img}.img
              set cmdline_method root=/dev/sda1 ltsp.image=ltsp/${img}.img loop.max_part=9
              goto ltsp

       The  ${img}  parameter  is  the  name  of  the  menu;  it  would  be "ubuntu" if you copied ubuntu.iso in
       /srv/ltsp/images/ubuntu.img and ran ltsp ipxe.

EXAMPLES

       Initial use:

              ltsp ipxe

       Regenerate ltsp.ipxe and reinstall the binaries:

              ltsp ipxe -b

       Copy the binaries from a USB stick before running ltsp ipxe:

              mkdir -p /srv/tftp/ltsp
              cd /media/administrator/usb-stick
              cp {memtest.0,memtest.efi,snponly.efi,undionly.kpxe} /srv/tftp/ltsp
              ltsp ipxe
