Boot into TrueNAS installer via iPXE

[ccy]

I have iPXE service setup in my network. It is working fine so far.

I download a VyOS ISO installer and the installer in my iPXE environment and this is the iPXE script:

Code:

set inst-dir http://install.example.com/vyos
kernel ${inst-dir}/live/vmlinuz initrd=initrd.magic boot=live nopersistence noautologin nonetworking fetch=${inst-dir}/live/filesystem.squashfs
initrd ${inst-dir}/live/initrd.img-5.10.116-amd64-vyos
boot

The script is working and I can boot into the installer from iPXE.

Next, I try to do similar configuration on TrueNAS Scale ISO:

Code:

set inst-dir http://installer.example.com/truenas
kernel ${inst-dir}/vmlinuz initrd=initrd.magic boot=live fetch=${inst-dir}/live/filesystem.squashfs
initrd ${inst-dir}/initrd.img
boot

But the script can't boot successfully. It show a message: No installation media found after fetching the filesystem.squashfs.
