Hello,

I have a dhcp proxy setup and need the possibilty to secure boot some machines.Problem is, that the standard grub2 version from ubuntu seems to have a bug.It forgets about the next-server option and sets the normal dhcp server as tftp server.So it loads the shim and grub .efi files, but then it cant load the grub.cfg because of the wrong tftp server.

After some experimenting it seems that fedora uses a newer version of grub in which this bug doesnt occur.If I take the shim and grub .efi files from fedora it gets to the grub.cfg but after I select the clonezilla entry it fails loading vmlinuz with “bad shim signature”
I guess that happens, because the shim from fedora cant verify the clonezilla vmlinuz.So my question is, is there a clonezilla build which can be loaded from a fedora shim?
