Topic: Boot error using GpartedLive over PXE
I apologise if this has been answered elsewhere: I have looked to no avail. Also pardon my ignorance on matters of *nix/PXE. Still learning.
I have a PXE server set up, and I can successfully serve up images such as Memtest. I am trying to get GParted added to my library of utils, but I'm running into strange problems. The initial image (initrd.img?) transfers successfully, but during boot I get a boot error.
Unable to find a live file system on the network
modprobe: module i8042 not found in modules.dep
modprobe: module atkbd not found in modules.depThe fault screen indicates /live.log file, which shows my NIC successfully assigning an IP address, followed by this:
Begin: Trying tftp -g -b 10240 -r /image/gparted/filesystem.squashfs -l /live/image/live/filesystem.squashfs 192.168.4.11 … tftp: read errorThe only reason this command fails is because the directory /live/image/live does not exist. If I set the local directory elsewhere I can download this file.
So the question is: why is that directory not being created. I've found the /scripts/live script, and by searching for tftp I found the relevant section where it attempts to transfer the file. A few lines prior to that (line 810 in my version) the /live/image/live directory should be created. But this is as far as I can go. I'm no expert on PXE images, or *nix scripting, so I can't work out why it's failing.
Now, my setup. Here's the entry from my pxelinux.cfg/default file:
label gparted
menu label GParted Live
kernel images/gparted/vmlinuz
append initrd=images/gparted/initrd.img boot=live config union=aufs noswap noprompt vga=788 fetch=tftp://192.168.4.11/images/gparted/filesystem.squashfsThe directory names/capitalisation are all correct. As I said above, even after the boot process had crashed out, the tftp command could successfully download the filesystem.squashfs file by simply changing the destination (local) directory.
I managed to add the debug flag to enrich the /live.log file:

I downloaded gparted-live-0.11.0-10.
Sorry for the length of this post, just trying to preempt questions for more info 
Thanks,
