[X2Go-User] pxeboot in Debian Buster (not booting, which pxelinux.0?)

[Luciano Andino]

Hello, I'm x2go user since some years ago. Now trying to install a new
PXEBOOT server. What I did:

1) Updated x2go sources according:
https://wiki.x2go.org/doku.php/wiki:repositories:debian

2) Then continued building system with instructions
https://wiki.x2go.org/doku.php/doc:howto:tce#building_your_own_x2go-tce_image

    $ apt-get install genisoimage git-core live-build live-config-doc
live-manual-html live-boot-doc lsb-release netcat-traditional
    $ apt-get install apt-cacher-ng
    $ apt-get install qemu-user-static
    # dpkg -l|grep x2go
    ii  x2go-keyring
2019.08.20+git20190820.118+10.main.1     all          GnuPG keys of all
X2Go developers and the X2Go archive
    rc  x2gothinclient-management
 1.5.0.1-0x2go2+git20191129.725+10.main.1 all          Management tools for
X2Go Thin Client chroot server


    $ mkdir /usr/local/x2gobuild ; cd /usr/local/x2gobuild

    # then created the three files
patchscript/x2go-tce-build/x2go-tce-config
    # applied patchscript and started to build

    root at pxeserver:/usr/local/x2gobuild# ./x2go-tce-build
    ....
    cryptsetup: WARNING: Couldn't determine root device
    cryptsetup: ERROR: Couldn't resolve device /dev/sda3
    cryptsetup: WARNING: The initramfs image may not contain cryptsetup
binaries nor crypto modules. If that's on purpose, you may
    want to uninstall the 'cryptsetup-initramfs' package in order to
disable the cryptsetup initramfs integration and avoid this
    warning.
    ....


    Build is done:
'./live-build-x2go-20200227200355-netboot-amd64-openbox-magic-pixel-workaround-buster'
    641641 bloques
    [2020-02-27 20:20:07] lb clean
    P: Cleaning chroot
    root at pxeserver:/usr/local/x2gobuild#

3)
    * http server installed. Both x2go-tce.sessions &
x2go-tce-filesystem.squashfs are accesible through niginx.
    root at pxeserver:/usr/local/x2gobuild# cp
live-build-x2go-20200227200355-netboot-amd64-openbox-magic-pixel-workaround-buster/x2go-tce-filesystem.squashfs
/var/www/html/x2go-tce/

    * dhcp server installed and working.

4) Netbooting
    4.1) atftp server working
    4.2) Copied x2go-tce-vmlinuz and x2go-tce-initrd.img to
/srv/tftp/x2go-tce
    4.3) created in tftproot "pxelinux.cfg/x2go-tce" (file reference to
x2go-tce/vmlinuz and x2go-tce/initrd.img instead, changed that)

    4.4) looking for a pxelinux.0 file:

    4.4.1) root at pxeserver
:/usr/local/x2gobuild/live-build-x2go-20200227200355-netboot-amd64-openbox-magic-pixel-workaround-buster#
    cp live-image-amd64.netboot.tar /srv/tftp/
    root at pxeserver:/usr/local/x2gobuild/live-build-x2go-20200227200355-netboot-amd64-openbox-magic-pixel-workaround-buster#
tar xvf live-image-amd64.netboot.tar

    #    copied tftpboot directory to tftproot directory
    root at pxeserver:/srv/tftp# ls
    advanced.cfg  install.cfg  libcom32.c32  libmenu.c32  live menu.cfg
 pxelinux.cfg  stdmenu.cfg x2go-tce
    hdt.c32       ldlinux.c32  libgpl.c32 libutil.c32  live.cfg pxelinux.0
 splash.png  vesamenu.c32

    ---> Result, system does not boot (ethernet driver fails)
    or

    4.4.2) Using old x2gothinclient_preptftpboot script
    ---> System boots but login screen offers to connect to an X server
somewhere in the Internet (seems is not using sessions file)

Thanks in advance,
