I have GParted setup almost identically to as described in the website help:

https://gparted.org/livepxe.php

The only difference between that the root directory is not / rather /GParted

The vmlinuz and initrd seem to boot ok.
The filesystem.squashfs is loaded via http and I can successfully wget it.

However, when it try to mount of the filesystem.squashfs, I have a problem as shown in the red box.

Mounting root file system ... /init: .: line 225: can't open '/scripts/GParted/live'

I'm not sure where /scripts/GParted/live is. I'm also not sure how it would get a directory in front of my root /GParted However, the system manages to find /scripts/init-premount

My PXE default here:

LABEL GParted Live
MENU LABEL GParted Live
kernel GParted/live/vmlinuz
APPEND initrd=GParted/live/initrd.img boot=GParted/live config components union=overlay username=user noswap noeject ip= vga=788 fetch=http://10.1.200.1/GParted/live/filesystem.squashfs
ENDTEXT

Where have I gone astray?

The /scripts/init-premount lives inside the GParted initrd.img file.

The error message suggests the system is running into trouble on line 225 of script /init within the initrd image.

The line 225 of that script is:

. /scripts/$BOOT

And the $BOOT variable gets its value from the boot= boot parameter earlier.

So, the mistake is in assuming that if you put the filesystem.squashfs file into a sub-directory on the web server, you need to adjust the value of the boot= option to match. That is incorrect.

The boot= option specifies the boot mode: local, nfs, or live. This causes the script system (= initramfs-tools from Debian) to run the corresponding script in the /scripts/ directory. /scripts/live exists in the initrd.img file, but /scripts/GParted/live doesn't.

So, change the APPEND line of your PXE bootloader configuration to:

APPEND initrd=GParted/live/initrd.img boot=live config components union=overlay username=user noswap noeject ip= vga=788 fetch=http://10.1.200.1/GParted/live/filesystem.squashfs

...and then it should work.

That was it. I didn't realize the boot= was a parameter as opposed to the initial boot directory holding initrd. Thank you.
