I made an Ubuntu 20.04 customized"customized" img via dd command from a USB disk drive. UsingI use servaServa as PXE server likefollowing servaServa tutorial tutorial.

The official Ubuntu 20.04.4 ISO PXE bootboots successfully. But whenWhen I PXE boot my customized"customized" image it properly downloads vmlinuz and initrd but will initrd triggers a kernel panic.

Question

It is right wayIs it correct adding a Linux asset to make PXE boot sequence like copyServa's repository by copying all the filefiles from an image file on root(root partition folder) to NWA_PXE/{my customized image name}?

If this stepmethod is correct. Maybe could it be the initrd filetriggers the kernel panic because it lacked some kernel module like SMB module or CIFS module on boot?

This is inspired by this article: Boot custom Linux image using PXE

The error code is:

[ 1.437739]  ---[ end Kernel panic - not syncing: Attempted to kill init! exit code=0x00000200 ]---

The ServaAsset.inf setting is:

Background

I made an Ubuntu 20.04 "customized" img via dd command from a USB disk drive. I use Serva as PXE server following Serva tutorial.

The official Ubuntu 20.04.4 ISO PXE boots successfully. When I PXE boot my "customized" image it properly downloads vmlinuz and initrd but initrd triggers a kernel panic.

Question

Is it correct adding a Linux asset to Serva's repository by copying all the files from an image file (root partition folder) to NWA_PXE/{my customized image name}?

If this method is correct could it be the initrd triggers the kernel panic because it lacked some kernel module like SMB or CIFS on boot?
